How do I only remove the Prefix LSC in the Customer Id

In Litium 5 we just edited the Stored Proc StoredProcedure [dbo].[Relations_GetReadableCustomerID]
But not it seems this isn’t used, cause we get the prefix again on new customers.

So I want the customernumber from Litium but we need to remove the prefix. Were using the Accelerator and the UserUtilities to create a person.

Litium version: 6.1.2-patch-1806150802

See the answer on How do I change the logic of Order number and Customer number?
