Yes, as you can see above, I  understand the intent of those two options. But if someone could further explain what's happening in the rule, I would be most appreciative. 

I'm guessing the first part assigns a name or ref if one appears in the tagging but understanding the logic of the series of "subst" filters following that is, for a newbie, quite challenging.

Hi Dave,

please check the documentation for --process-destination and
--process-exits:

If I got this right, these option mark exits so that Garmin knows where
they are where they lead.
