Is there a Montage OnSectionStart default notify or event?

I’m trying to reset one variable each time any montage section starts (including with looped sequences on each loop). I know I can do this with notifies but I’m looking at a potentially large amount of sections, and then having to recreate the same notifies again in my production version (when I port this across). Would make things a lot easier for me if I could make this dynamic.
Does one exist, or is there a way to bind an event to the beginning of all of a montage’s sections from a single call, or some way to get a section’s play position/ratio or something?
Thanks in advance.
