ModelingTools: add support for writing to selected group layer, as well as new group layer, in ConvertToPolygonsTool (GrpGen in UI). Also add support for setting groups from existing layer, which (combined) allows copying groups between layers, duplicating existing layer, and so on. #rb none #preflight 630e3856e11248377555f234 [CL 21704364 by Ryan Schmidt in ue5-main branch]
