I second other members input that as long as it has not been in process and final determination has not been done then you should be able to add docs..if I am not mistaken that is what I understood...Good luck
Operational Bulletin 120 states the process for this issue:

C) Incomplete applications
Applicants are expected to submit a complete application including supporting documents identified in the visa office specific kit. However, submissions will vary in quality and completeness. Procedures for the most common scenarios visa offices may encounter are outlined below:
•The R10 completeness check has already been done at the CIO: Although applicants must submit an application to the CIO and (if referred to a visa office for a final determination of eligibility for processing), a copy of the application to the visa office, this is one application for permanent residence and the R10 check is only done once.
•The visa office will receive and assess the applicant’s submission as-is: Visa officers should proceed directly to a final determination of eligibility against the MI. If the application is determined to be eligible for processing, the case should proceed directly to a selection decision based on the information on file.
•Insufficient evidence of meeting Ministerial Instructions: Visa officers will assess the application on the basis of the information on file. If the applicant’s submission is insufficient to determine that the application is eligible for processing, a negative determination of eligibility should be rendered.
•The sample letter in Appendix D of OP 6 should be sent to applicants who receive a negative final determination of eligibility for processing based on what they submitted within the 120 day deadline.
•Missing SELDEC documents: Visa officers will complete the final determination of eligibility on the basis of the information on file. If the application is eligible for processing, visa officers will complete the selection review based on the evidence presented. No follow-up request for the missing document is required.
Exception: Section 10.10 of OP 6 states that applicants who submit other evidence in writing that satisfies a visa officer that the applicant demonstrates language proficiency of at least Canadian Language Benchmarks (CLB) 2000 benchmark 4 but not the proficiency levels claimed, should be given the opportunity to provide conclusive evidence. Visa officers should proceed in accordance with procedures outlined in section 10.10 of OP 6. Please note though, that if the other evidence in writing only satisfies a visa officer that the applicant has demonstrated language proficiency corresponding to the CLB 2000 benchmark 3, there is no requirement to invite the applicant to produce conclusive evidence.
•Missing documents / information related to admissibility: Any documents or information required to complete the admissibility review should be requested once SELDEC is passed. Missing admissibility documents should not hold up the final determination of eligibility or selection review
