Currently there is no method to assign the revision scheme duing item creation, including when assigning items to files.
We use two revision schemes... our default is numeric based starting at 0. We use "0" as the released to production revision. Our proposal scheme uses letters and starts at A. The way it is now I create a new item, which is assigned a revision of 0. I save the item and then adjust it to A. This consumes the 0 which cannot be used again. What I'd like to see is the option to select the revision scheme while both creating the item from the item master AND duing item assignment when assigning items to files
