Topic: Tag GL Accounts Receivable to a customer

I want to tag the Account Receivables Account to a Customer (Cash Sales) to GL Account "Cash Account".

But when I drop-down to select account, it doesn't show the Cash Accounts. I want the Account Receivables Account to be tagged to Cash Account, but FA doesnt let me do that.

Check if it is made into a "Bank Account" whether it would work.
