Sharing the same history db between users of same host, and add filter by user

I wanted to have my root user history available on my regular user history, but the current atuin solution only stores hisotry per host with the ability to filter per session, global, directory.

A configuration hack i tried is to point db_path of the root on the regular user history.db ( db_path=/home/regular/.local/share/atuin/history.db ). This will make both users history be stored in one database. This works without any problems, both users read and write from same history, but it lacks the ability to filter by user even tho the database contains a column hostname storing as value hostname:username.

It would be better if atuin supported having same database shared among users, which represents the GLOBAL with the ability to filter it to USER scope.

Thank you.
