I have an apartment block that is a group. Within that each floor is grouped (or a component if repeated). Within each floor I have a number of components (windows, doors, balconies, or apartment types). Now I name the apartment block Scheme 1. Now I want to do a second scheme (scheme 2) that has larger windows and different balconies. Is it possible to have a script where if I right click on scheme 2 apartment group and make all components unique within it?

chaddad, I think this plugin does what you describe.

Makes components in the selected group unique
