(Request) More Custom Random Groups

I love the custom preset random feature. The feature that allows you to select number of civs that you want to randomise.

The problem arises when I want to see select civs in select map style in ranked play. For example, say I want to select certain naval civs in a naval map, desert civs in desert maps, meso civs in meso maps. Quickly changing over the custom list within 1 minute after map gets selected is not very ideal.

Can we please have more presets for custom random than just one? So we can save presets and switch them as per our preference more easily.
