Functions>custom>Call Macro Function
This node will allow you to call any custom function inside a nested macro and display input vars and output value. Will also work for a macro nested in a macro but must always be called from the root graph of the nested macro.
This allows the user to create a library of common functional use and then use those functions in a root graph. Very clean root graph.
Provides a dropdown menu for all functions in the macro graph. No misspelling complications.
