Merging places should work for community curated locations, but what about places added from external sources? In this case, one place is located within another one (Lima, LP, PE within Lima Province, PE, and Callao, CL, PE within Callao, PE).
I suggest making the mother place the main one, as sometimes I’ve found myself using the second one instead of the main one for some projects, and adding species to the main one doesn’t update the second one, even though the boundaries are exactly the same.
Another question, if I merge one point of interest with a previous one that was made, which one will be the main one? I’ve made one with the correct boundaries and added species to the list, but there’s a previous one with less species and broader boundaries.
