Is your feature request related to a problem? Please describe.
When using {{ }} or Custom JS queries, it does not know about any JS functions that I made in the Advanced Settings. This would be nice. I preface all my global functions with globaljs_ .

Also does not show autocomplete options from app level JS functions.

Describe the solution you'd like
I would like to start typing "globaljs_" then have the auto suggest show me all the functions.

Describe alternatives you've considered
I have to go to Advanced/Settings every time to look up the name of the function.
