GMSI Help needed again

[Ironside]

Hello, this time I'm in need of a script that does this:

I select map A and map B, then it should take all units, spells, upgrades and buffs that map A has and map B hasn't and copy them to map B.

I need this urgently because I'm trying to port a lot of things from an old version of the map into a new one.

there is a export/import function ?

That would replace all the newer data, I just need the old one + the new one.
