Hello @RandS thanks for your post. Wow, that's a lot of accounts. Not sure if this works for you, but I'd explore setting up different "locations". The deposit may still come under one though. I'm not sure if you work with a tax and accounting professional, but with that many accounts I would think they would have some advice for you about streamlining your operations.
You can see this help article about setting up locations. I hope this might help answer your question.
