[Therion] Controlling colour-by-map

I like the colour map-fg map command, but with a a big system I need better control than to have each bottom-level map coloured differently. Is there any way to control what get's coloured? e.g for an overview map I really want each cave to be a different colour. But some caves are made up of several maps. Currently each of these gets a different colour. Can I select which maps are considered for the colour-allocation, and/or allocate colours to maps?
