Assign Income to Project Without Invoice

Assign Income to Project Without Invoice

Hello,
Fairly new user here so apologies if there is a really obvious solution here that I am just missing...

I have hundreds of small deposits into a bank account that I want to assign to a project but do not want to have to create an invoice every time one of these transactions hits my account. It seems like there is no way to do this when I mark the transaction as Other Income or Sales Without Invoices. Am I missing something or is there a workaround that anyone knows of? 

Thanks!
