structure definition at master level ?

hi ,

business looking for option to define primary structure at master level and same structure should auto-assigned at child org level. currently business is manually assigning structures to individual organization. does anyone worked on similar requirement ? please comment.

below option tried :-

Option 01 : - Assigning structure to child org through propagation Rules under change orders , we tried with this setup but won’t work here because pre-requisite is to have structures available in master and child orgs. only then changes would be propagated to child orgs. these rules won't work to propogate structure creations to child organization.

Option 02 :- creation of common structure or copy from structure ( this will also won't work for desired requirement )
