I have 2 visa fee receipts for my parents as i created 2 profiles initially. can i add them under one account now

I have created 2 profiles for my parents and paid their fees separately. Now I have 2 receipt numbers. Can I add one of them to another account using 2 different receipt numbers?. Please help me with this situation.

You should be able to add one of your parents to rhe primary as dependent. In case you need further help contact VFS.
