rigging skinning "shift select" multiple vertix group

Hello Again :) I think i am demanding too much :D but i think that will help us all.

After attaching the mesh to the rig "using automatic weights" it shows all existing vertix groups. To avoid this clutter i clean vertex groups by deleting them all "manually"

For example, Tongue mesh needs only three tongue bones weights. So removing all other weights become hectic as vertex group tab don't allow to select multiple vertex group at once "Shift select"

So my requests are:

01 .Alow selecting multiple Vertex Groups

02.It would be super cool if i can skin only selected joints. eg. for tongue it should be like: select 3 tongue def bones and than skin. And it should show only that 3 bones vertex goup.

Cheers :)
