Hi , I wrote a simple plugin that will store rig / performance / preset file in your track in the DAW with the session.
You can use right mouse button to cop/pase directly from/to RigManager or try to use drag-and-drop.
Tested in :
Logic (on OSX) and Sonar,Reaper (Windows)
Mac OS X AU/VST3 : https://www.dropbox.com/s/c59awn5bpuyzi8i/Rigkeeper.dmg?dl=1
