Supplier Bank Account Creation is creating Bank and Branch in Cash Management Module

Content

When we are creating supplier bank account information it is creating supplier Bank and Branch information in the system and dont see any flag as External. is this standard feature? if we have 1000 suppliers and theoretically each supplier has separate bank account, then there will be 1000 bank accounts in the system which is becoming very confusing, is there any other solution for this?

Appreciate your advice, if any for the best practice.
