True. I admit this would be rather complicated but as I'm new to SA and
everybody has SA in high regard I hoped it could be capable of doing
such a thing.
Thanks for taking time to reply and for all information you provided

If I can just wrap this up, do i understand correctly that this would
the functionality of "joined eager loading", except applied to something

I think you can get pretty close to that just using plain UPDATE..FROM
and spelling out the joins you want. Recently we even got UPDATE..FROM
a JOIN b working.
