Very quick question MHS3

So with Excursions, you can get the stat bonuses and Environmental Skills from two different zones, right?

Can anyone elaborate on the specific conditions? I tried populating a monster in both Azuria and the second zone, but I tried sending a Monstie born in the second zone to an excursion in Azuria, and no dice.

(Ngl it could possibly have been because I went to the excursion menu immediately after releasing the monsters but idk, i could use a little help)
