Hi all,
I see a lot of people have been requesting this so I thought I'd post this here.
I built a grouped RecordID tool that allows you to create a record ID that uses one or more fields as grouping:

Say you have data like this:

and you want to create a RecordID field, but rather than just counting from 1 to 5, you want to group it by the District field, and reset the count at each change in this field, then you can now use this tool to do exactly that:


Nice and simple but a useful bit of functionality methinks.
Thanks to the handsome and talented @joshuaburkhow for making it look pretty and helping out with some of the testing.
Enjoy.
