@Thairne in Tau/GK formations I've used entry groups to provide all elements in formations. So, say you need 1 captain. Make a group, set default to vanilla cap, min/max1 (on group) and g2g. Troops 1-6 Assaults? group, default Assault, min1max6, voila. It's not exactly great in terms of nestedness in views, but quite nice in general. No modifiers etc.
