Device ports

I’m away from my gear at the moment, but I was thinking about ways to solve a particular configuration issue I’ve having with my new setup.

Is it possible for a particular preset to read from MIDI DIN port 1 and send out to MIDI DIN port 2?
Basically using both device 1 and 2 in a single preset.

From the documentation, it looks like it would be possible if I messed with the device/port values as needed for the incoming and outgoing sysex transfers. but I don’t know if on startup a particular port is tied to the preset exclusively or not.
