Hi @yaniv691,
Thanks for giving that a try, it seems likely the only way to go about this would be through some custom code.
I'd love to look more into this though if you wouldn't mind sending through an admin login. I could then post back here with a solution.
If that works for you, simply submit details through here:

Just select "I have another question", then in the Subject, include "ATTN: David" with a link to this thread in the message.
How does that sound? :)
Cheers,
David
