XF 1.5 Modifying another add-on's template


Active member
I'm making a template modification that modifies a full custom template created by another add-on.

Is there a way to ensure that the other add-on's template is loaded before my modification will attempt to make its changes?

The Execution Order seems no use here, because the other add-on's custom template is not a modification.

Or are all add-on templates loaded first and that's not something I need to worry about?
