@Matt you can create a custom record and register all viewing data with user event script

Do you mind explaining a bit more as to how that works?

You would need to create a custom record, and create a user event script. Attach the user event script to all the records you want "viewing data" on. The user event would trigger in VIEW mode. You could get the current user's info with

N/runtime

and could write whatever data you want down to a custom record.

This is a not great solution for that problem.

I agree, not sure there is a great solution for storing people viewing stuff.
