I believe I understand what you’re asking for, but we’re limited in helping with customizations, per our Scope of Support / Terms.
If you need some coding help, you may want to ask your developer or reference our documentation and list of known customizers.
I think it could make sense for the overwrite to only overwrite data specific to the event details and not the WordPress-specifics like the category the event belongs in. I didn’t find that as an existing feature request at our plugins’ UserVoice page.
Please do add your feature request there.
This allows others who are interested in that feature to easily voice their support. We frequently review suggestions there to find out which ones are popular, then we implement as many of them as we can.
Once you post it, feel free to link to it from here in case anyone comes across this forum thread in the future.
