Is this something that can be edited? It appears to be an internal composite of three fields.
 
The problem is that Customer ID is hard to pick out between the customer name and phone number. I'd like to BOLD it, and/or put more room between, but can't figure out how to do that.
 
I've temporarily made visible and bolded BKAR.CUSTCODE that is already on the form, but for some reason is not Visible, which is a help.
