Customisable reference numbers for Improvements

The current reference number structure for Improvement reports gives a range of I00000 to I99999 across all portfolios. Having been with Promapp/Nintex/Process Manager for over ten years now, we're quite rapidly approaching the end of that range. We've just hit the 80000s, less than 12 months after hitting the 70000s. With our business growing quite significantly, we're expecting to run out of numbers in approximately 18 months.

I contacted our account manager and was told there is the setting to customise our own reference numbers for each portfolio, however that turned out to be incorrect, referring to the "Enable other reference field" function which only allows for an additional manual entry field to be used at the assigning stage, it does not replace the IXXXXX number.

My suggestion is to implement a setting enabling a customised reference number prefix for each portfolio. (E.g. INC00000, HAZ00000, P00000, ED00000 etc.)

Even just being able to change the letter I to something else would help reduce issues with people struggling to find their reports because the sans serif font makes them think the I is a 1.
