eCart Discounts (Rules) [Copy]

A 'copy' function to allow (e.g.) discount rules to be copied would be nice. Three times, now, I have wanted to set up discount schemes which are essentially the same, but only vary in the amounts that trigger them (5% if ..., 10% if ...., 15% if ......). It proved easier to go into the relevant PHP file in the WA directory and copy,paste,amend code in the two locations there than it was to try to remember what exact triggers and session variable names plus values I had set up in the original one. A "copy this discount" option in the eCart interface when you have the one you want selected would have been great, because I could then have worked with that copy. A small labour-saving tweak ... coming soon???!!!!
Thanks a lot.
Bye.
