Creating Subform to be used in diffrent Forms

Hi community,

I want to make dozens forms.
Most of the forms will have some repeating fields like name, email, etc’ .(about 10-20  fields).
I may have few(2-3) “Common SubForm”s (different groups of questions repeating ).

From time to time field will be add/ delete/ edit to the repeating so it will better for me to treat those repeating fields in one place and just once.(on specific “Common SubForm”)

So, far i didn’t find any solution to this. i thought on linking forms to the “Common SubForm” but i want those fields to be saved together. (I’m planing on sending them using webhook on the submit)
