Nothing complex just a menu system for geos, like the one to the send multi generals in one go, so that you can select and send more than one to search for a certain type of deposit ie select iron deposit from menu then tick/select the geos you want to search and they all go at once
this could even extend to the explorers with same system, select type of search treasure or adv then select size of search then select which explorers you want to go couldnt be easier
