Select an audio track
click the little arrow and select 'edit DX FX'
In one of the four boxes, scroll down to the bottom and click 'add VST'

browse to the dll file for the plugin (this will depend on where you saved it)
Once added it will appear in the list from then on as long as you do not move that dll file


I do not work here, but the benefits are still awesome
