It would be great to be able to create Dispatch'r rules that run against any item in a service catalog category. I have to specify each item, which means if I add an item, I have to remember to go find the rule and add it there as well.
Thanks for the feedback. This is already in the pipeline and should be out shortly.
This is on our long term roadmap. I'll certainly keep you posted if there are any updates.
Came across this post and wanted to let you know that this feature was added to the product some months back.
