Is there any built in way to tell when the data in a custom data set was last updated? If not, what would be the best way to proceed to build that in for one specific group?
As usual, the data can be edited by the administrative user logged in to civicrm OR it could be edited via a profile. In my case I know the profiles in advance, so could rely on the profile ids. These are always 'on behalf' profiles. Not sure if that's important.
I'm thinking I could create a custom "last updated" field in the data set, and then update it through a hook, but not sure if that's the best way. Thanks for any guidance.
