@woland No I don't think that will help as the ports pertain to what midi device you're connecting to. Inside the sysex actor is a script you have to write, then you insert perameter values using 'P1' 'P2' etc. There are workarounds where I trigger specific sys ex actors with some characters pre determined.
It would be a great feature to be able to put way more parameters into these actors generally. Same with the text formatter actor
