Stopping process after first match

I am running a trial version of this product and will definitely purchase it if I can make this rule work. Currently, this is what I'm doing:

I have Hazel watching the modified time of all files in a certain folder. Any time a file gets modified, I have Hazel run an Automator flow that runs Transmit sync. So far so good.

Issue is that if I save a JS file that then gets minified into another file, Hazel has Transmit open twice and sync twice. Ideally, I only want the sync to happen once. Another example would be saving a .css file that then has an accompanying .css.map file compiled. I would only want the sync to happen once. Is this possible?

It might be better to monitor one folder level up and have your rule match the folder instead of the files. If you have a deeper file hierarchy you need to keep track of, check out this thread (it uses the Sync action but the rule conditions should still apply): viewtopic.php?f=4&t=1593#p6500
