Reset Field for All Users

Hi,

I run a site that has a seasonal ID associated which each user from an external resource- the user has to input this manually and there’s is no way around that. For the sake of this discussion let’s call the metakey ‘external_id’.

Every season this ID resets- therefore I would like to be able clear all users inputs for this specific field (‘external_id) inbetween seasons.

Being able to clear it will be very handy and an extra bonus would be a means of notifying users to repopulate the field with their new ID- if either or both of these tasks are possible it would be fantastic.

Thank you 🙂
