Reset Object Layout to (new) Template (with new relations)

Is your feature request related to a problem? Please describe.
I have created myself an Object type for Persons / Freinds / etc and have already created some Objects, i.e. persons that i know. Now i also want to create an Object type “family” to link to every person.

Describe the solution you’d like
All fine and well, but now that i have added the relation, i dont want to add the line with family: for every object. I think it could be helpful if there would be a button to reset the layout of an object to one of its types templates, and if possible even keep the entries i’ve made bevore (say i already added a phone number in the “phone number” relation of my object, i want to keep that and just shift according to the new template). I’ve had that issue several times already, this one is just an example

Describe alternatives you’ve considered
Then also nice would probably be to be able to reset all objects of an type to a template or even be able to select the objects you want to be reset from an type’s list. that would be great!
