Vertex Group Parsing / Globs

Hi Developers,

I would like to propose a more efficient way to use parsing of vertex groups.

Current Use case in blender 2.79 : While using modifiers, we can assign only one vertex group per modifier to define which vertices or area of a model is affected by that particular modifier.

Proposed feature and usability:

Ability to mention more than one vertex group in every modifier using a separator ( may be a "+" and a "-" sign? )

For example, if we are using the mask modifier, and we want to hide the both the hands of a character( which are already defined before as hand.L and hand.R) , the user will input "hand.L + hand.R" in the vertexGroup field.

We can also add support for wild Character "* " ,

so, user can simple type hand* and both the groups will be taken as input. Please checked the attached thumbnail for better explaination. I am ready to explain further use-cases and strongly believe that this small feature can make blender more powerfull and less cluttered.

Thanks, Jayraj
