Couple of options I can think of:
- Badges would work…you’d make a badge per procedure. However, if you wanted a date you’d end up with quite a lot of badges. Badges also don’t display on the profile unless you open the badge page…
- You could use titles, which would appear almost anywhere their username does. But there can only be one title…you’d need to figure out how to handle multiple procedures.
- You could also use custom fields. They would appear on the user card and the profile. Similar issue with titles determining how to handle multiple procedures. Benefit of custom fields is you could make more at any time.
