We would LOVE to have the Bill Group ID option identify the account sub ID number to individually choose the accounts needed in that Bill Group ID, then not all accounts beginning with the same account ID are included. We use the PID associated with a specific apartment complex parcel as our account ID with a unique sub ID for owner and tenants, so when adding a Bill Group ID it adds the Bill Group ID to ALL accounts beginning with that account ID totally disregarding the account sub ID. We have apartment complexes with hundreds of utility accounts in the complex name and currently have to process 1 at a time in a payment batch using the shopping cart.
