Oh no, I've been so swamped I forgot to post back here..
I added support for this in version 4.7.2 so you can do it right now. It works by letting you choose which cards to ignore.
To ignore a card, you'll have to have been connected to it at least once since installing version 4.7.2 or above. Once you've been connected, it'll show up in the in-app settings -> Advanced page -> Discovered Wi-Fi Cards.
In that list you can choose to not receive from the card(s) by flipping the switch. If you have a lot of cards you can also swipe the row to rename the card to something more descriptive than just "Toshiba FlashAir".
Since this can get really cumbersome if you have 20 iPads and 20 cards you have to configure, here's what I would do:
* Start out with 1 iPad and have ShutterSnitch detect the first card.
* Go to the in-app settings -> Advanced page -> Discovered Wi-Fi Cards and swipe from right-to-left on the card for the option to rename to what you'd like to call it.
* Toggle the green switch-button OFF so ShutterSnitch won't connect to it.
* Repeat for all the other cards.
* Now that you have registered all the cards, go to in-app settings -> Advanced page -> Share Configuration and check the 'Settings' row. Then Share the configuration to your computer (or some place that has a text-editor application).
* Edit the configuration file (it's just text) and remove all other settings, so it only includes the DiscoveredWiFiCards information. Example:
- Code: Select all

* You now have a configuration file that you can send to the remaining 19 iPads to import all the cards. Afterwards, on each iPad, go into in-app settings -> Advanced page -> Discovered Wi-Fi Cards and turn on just the card(s) you wan't to receive from on that device.
