Is it possible to do Alt-n (select-next-sibling) but in a multi cursor way?

More generally I'm looking for a solution to turn TS commands that selects things in a multi cursor fashion (example: multi-cursor all the elements in a collection)

Doing that will also allow exchanging the current text object with the next easily, which is not possible to do easily now AFAIK.

Ideally, this could be the default, and then you can do merge_selections if you want the selections merged (like it is right now)
