Different SubClients using same EIN?

Hello Team TabaPay 👋

We have customers that have a number of DBA's (do business as) using the same EIN. We've as such, created different SubClients for each DBA.

Question is, on the TabaPay side, is there a distinction made? Do all SubClients with the same EIN get grouped as one when it comes to accounting? When it comes to generating 1099's end of year, does TabaPay generate one 1099 for them all?

If all same EIN SubClients get grouped into one, shouldn't TabaPay perhaps make EIN's unique per tenant, and disallow creation of SubClients using non-unique EIN's?

Thank you!
