HELP: Linked sponsorship application to sponsor's GC key...Any way to fix this?

[whoisbuzzlightyear]

Hi everyone,

I made a mistake linking my common law partner's PR application to my GC Key; I'm the sponsor, my partner is the principal applicant...

I just learnt that one application can only be linked to one GC key...Is there anyway to correct or fix this? Would this be a serious mistake?

Thanks!
