Separate with and by vertex name group

Right now Separation creating from existing object .001 instance and have option by selection , by material , by loser parts . Proposal is to Separate :

• by vertex name group if exist or if not exist to give option to create name when selecting option from menu new name
• by vertex name group without edit mode, but from outline or material list by RMB click to reveal menu and this option

After this operation user need this:

• blender.community/c/rightclickselect/my7R/ Move here (RMB on collection in outliner)
