Apart from the normal additional anemometer, Temp/Hum/Soil sensor transmitters can MB Pro handle true multiple ISS (as such) configurations?

For example (extreme case) could MB Pro config be

Station #1: Integrated Sensor Suite (ISS) - Anemometer only
Station #2: Integrated Sensor Suite (ISS) - Temp/humidity only
Station #3: Integrated Sensor Suite (ISS) - Rain collector only
Station #4: Integrated Sensor Suite (ISS) - UV sensor only
Station #5: Integrated Sensor Suite (ISS) - Solar sensor only

Or is there a limitation similar to Davis?

yes, should work. If ISS is just equipped with a few sensors that should work,
although I did not test a secial setup like this. Dedicated Wind or Rain or Temp/Hum
stations is something which can also directly selected as station type in Meteobridge.
