Component that Rolls User Specific Data Up

Is it possible that a component that rolls up user-specific data could be created?

Yes. Though, components donโ€™t roll up data, the roll up column does. Use a roll up column on any column of data. If the column is a user specific column, then the roll up is user specific. If you preview the app as different users, youโ€™ll see that this is the case.
