Delay Running a Rule

Hi all, first post and new user of Hazel - looks very interesting and has great potential.
I'm using Hazel to run a script to transfer images from Lightroom into Apple Photos. I export from Lightroom into a Temporary Folder, and Hazel then imports the contents of said temporary folder into Photos, then deletes the files. It's a one-click workaround to transfer the files, beautiful.
The problem I have is that as soon as the first file hits the temporary folder Hazel runs the script. While it picks up most of the files there are occasions (especially if I'm transferring 20+ files at once) where some files are missed, and I then have to re-run the Hazel script to check the folder and it goes "oh yeah!" and moves the last ones over.
What I really need is a way for Hazel to see activity in the Temp Folder, and then WAIT. Either until there is no more activity, or for a set time - I was thinking 60secs or so should be enough.
The rules I have at the moment are as follows:
Nice and simple, but being a code novice I can't really figure out a way to make it stop and wait before it runs it. If anyone can point me in that direction (make it simple, as I say I'm not that technically savvy any more!) I'd be most grateful!

The rules I have at the moment are as follows:
If all of the following conditions are met
If Kind is Image
Do the following to the matched file or folder
Import into Photos to album All Photos
Move to folder Trash
