- add ModelingToolTargetUtil, contains helper static functions for interacting with ToolTargets without having to manually cast things/etc - add StoredMeshSelectionUtil, contains helper functions for interacting with stored selections - USingleSelectionMeshEditingTool now can automatically grab an available stored selection, if it exists - Add GroupTopologyStorableSelection::GetGroupIDs() #rb none #rnx #jira none #preflight 60b0282063fc6e000133ed3d #fyi semion.piskarev, lonnie.li [CL 16499566 by Ryan Schmidt in ue5-main branch]
