Adding a Random Number Draw to Vasl

I would like to include a button that allows me to draw a random number from 1-6 (for example) without drawing the same number twice. Does anybody know how I could go about doing this?

A regular dice button will always generate a random number within its range. There’s no way to prevent it from not rolling a previously generated result.

However…

You can use a hidden card deck with cards numbered from 1 to 6 (for this example). Once a card is drawn it won’t be drawn again until the cards are returned to their original stack.

Is there some way to create a card deck for vasl as an extension?

I'm sure an extension deck can be made. However, VASL is quite an extensive mod with lots of versions and I haven't been involved in its history in any way so I'm reluctant to give you advice on how to do that as it may mess something up. Perhaps one of the VASL gurus can help you out on that.

Anyone???
