Sync everything except ZIP files?

I have a basic sync rule working fine, but decided today that I want to try to exclude ZIP files from the sync, since I have a lot of folders that contain photos as well as a ZIP file containing those photos that I send to my client. There seem to be a few different options for excluding ZIP files (by extension, filetype, etc), but is there a preferred method? Also, given the sync setup below:

where would I put the ZIP exclusion? I have tried a few different options, and have (at worst) caused sync to stop working completely or (at best) not actually achieved my goal, as ZIP files still sync.
I thought about splitting this into its own rule and just have it run a sweep for ZIP files every 10 minutes or so on the destination, but don't want to end up with the two rules fighting each other, with one deleting the ZIP files and the other noticing the folders are no longer in sync and copying them back.
Thanks for any pointers!
