I often am patching fixtures with multiple parts that have a remote dimmer (scrollers, VL1ks specifically) on the fly with the iRFR and want to be able to patch the lamp into Part 2. I haven't figured out a good way to do this in the current version of the iRFR (same functionality would be expected on the aRFR).
The only work around that I have figured out is to patch Address @ Channel, but that adds a third part, leaving the 2nd part empty (that was already created when assigning the type).
