How to revert to custom screen after screen generation in BDT

Hi Experts,

I had a custom tab "territories" in general data of BP transaction for a "Y partner function" . However i have performed screen generation in BDT and after that I dont see the custom tab in BP for that partner function.

Is there a standard way to revert to the previous configuration and re-generate the custom tab in BP ?

Or doing the configuration again and moving changes through TR is the only way to achieve this ?

Thanks & Regards,
