Can a family application case submit Biometrics in Two Countries?

[RoRoy]

Hello everyone, I have a question for BIL: My wife and I applied for the CEC while inside Canada, and we just received the BIL. However, she is currently outside of Canada. Can she provide her biometrics in another country while I do so separately inside Canada?
In addition, the country of birth on my BIL is wrong, can I still use this letter to submit biometrics?

Thanks in advance.
