Associated account in use, unable to link feed

Hi,

It says my bank feed is ready, but I am unable to link the feed to an associated account as the account is already being used.

The account I want to link it to has transactions as I imported the bank statement while I waited for the bank feed for this credit card.

is there a way I can merge the bank feed with the prior reconciled transactions into the one associated account?

Hoping the wealth of knowledge in this community will help me to find a solution that doesn't involve undoing and redoing all the previous reconciled transactions, but I appreciate your help either way.

Thanks

Rachael
