Run Adobe InDesign Script with BTT (without first establishing custom InDesign keyboard shortcuts)

I'd like to run a jsx file from the Adobe InDesign Scripts panel or from the jsx file location without setting up a keyboard shortcut in InDesign for my BetterTouchTool gesture to trigger. I've explored the Run Real JavaScript BTT action with no success.

Has anyone done something similar?

I'm hoping this would be as simple as putting in the file path to the specific jsx file I'd like to run for each gesture. A couple side notes, I have numerous scripts I'd like to trigger, and am running out of keyboard shortcuts. Also, scripts within the Scripts panel of InDesign are not accessible from a menu command.
