Multiple user with shared sheet and unique checkbox

I am currently putting together an app for a collection of items. The items are preloaded on a sheet over multiple tags. i would like each user to have their own unique checkbox values to track their personal collections. cant figure out the settings. Suggestions?

There is a feature in the works that would resolve this, but for now you would need to set up per user data and make a row for each user that contains the their email, so only they can see their own row to update.
