Mail form determination based on Multilevel Categorization

Hello Gurus,

I created different mail forms that I can select manually when creating an outbound email.

I set up the outbound email as a follow up document of a service request.

I was wondering if according to a value selected from the multilevel categorization I customized for my service request, a mail form could be automatically

determined when I create an outbound email.

I do not know if it is a part of SAP standard, if yes could you please advise?

Thank you very much for your help.

Best Regards.
