Notification when all rules complete

I am trying to implement a photo processing workflow using Hazel. These are the steps:

1) Recurse through camera card directories and copy new photos to local disk
2) Run script to send Pushover notification when all files are copied
3) Run script to unmount camera card when all files are copied

#1 is no problem. Based on some other tips, tricks and sample rules, the files are being copied over correctly. However, right now I'm getting a Pushover notification for every file that's processed. (I haven't tried #3 as I think its the same dependency) Is there any way to tell Hazel to do something when all rules are complete rather than for each file?

The way you have it set up, it's matching for each file. You need to look at it again in terms of processing a whole folder. You can try using the sync action for that as described here: viewtopic.php?f=4&t=1593&p=6500&hilit=sync+rule#p6500

After the sync action, you can add actions to do the notifications and such.
