Adding Needs?

[Viceroy]

Is there a way to add other needs to a colonist, or to another pawn entirely, like for instance say I want to add a 'water' need for colonists, or a 'relaxation' need. Is this possible at present or not at all?

since there is no limits on assembly level, i will answer "no you can't do it via XML defs"
