It would be very useful if the Wait For Event and Event-Triggered Source activities allow matching an event trigger parameter by constant value, rather than by label.
For example, suppose I want to wait for an item to enter through port two in a Wait For Event. At the moment, I have to create an Assign Labels activity that creates a label "port", set it to 2, then in the Wait For Event I can "match" the Input Port to the label.
It would be pretty cool if instead of just a "match (label)" option, there is also a "match value" option so I can just type in "2" into the first column and select "match value" from the second column.
Using an Event-Triggered Source, it's even a bit more complicated: before the token is created it has no labels, so I have to create a token for all entry events, grab the input port to a label, and then Decide whether to keep them or throw them right into a sink.
There it would also be nice to have a similar setup to the Wait For Event option, but with only the "assign" and "match value" options and of course not "match label" and "insert at front".
