External Tools "autorun" on save with settings like for other tools

Use Case:

I want to run cmake file formatter on save of cmake files in QtCreator.

I want to run gersemi cause the cmake-format project is more or less dead and the "introspection" features of the cmake-format is not as good es gersemi

If i configure "gersemi" as external tools, formating is ok, but i have to trigger it by hand.

Could External tools get an "execute on save" with the same "generic" settings like e.g. cmake-format or other tools:

• Execute on save
• Execute for Mime-Type
• Execute for Project files
