1- Customer credit limit history
I’m using the Customer credit group and it is working fine. However

This feature is header and lines.
Header: Customer credit group where we set the credit limit
Lines : Customers list.

Scenario: Customer orders exceed the credit limit and we need to request at the same insurer or at another one for a new credit limit amount.
If we need a history. Is there way that we can end the actual credit limit from the customer credit group and start a new one and keep the history.
If we could update customer credit group credit limit WITHOUT overwriting.
Eueler 101 / 50.000
Eueler 101 / 75.000

2- Using an insurance and guarantees is done only at the customer level.
If we could also update the insurance for a customer credit group as well.

Thank you !
