How to merge 4 identical islands into one?

So, im trying to merge 4 identical islands into one so I can use the same texture on all the dresser handles. I’ve looked everywhere and found nothing. Any suggestions?


Unwrap one, select all the rest first, unwrapped object - as a last and Ctrl-L -> Transfer UV Maps.
Another would be - texture one and duplicate where needed.

Then, if you join objects, islands are equal and overlap automatically.

Ok that worked. I’ll have to write this one down for later XDD
