Installation node dropdown of functions from script editor

I was wondering if its possible to get a list of the functions in the script editor from the Ur cap. I have a ur cap that adds a slew of functions to the editor. I would like to access these functions from a list. I have some sample code for sending script functions to be executed automatically from JBM’s Script communicator. Is this possible to access the function list from the URcap.

Thanks in advance
