Feature Request - Make xcv Multi-session usable

[mdtareque]

Currently i can't do two 'xvc x *' in two different directories and then paste them accordingly. So , if i do 'xcv x *' in one bash session, 'xcv v' in other bash session it works ( and this functionality should be retained). But can you add functionality, so that i can hold more than 1 set in the xcv cache and paste the required one with some identity as needed.
