XF 2.0 Query to force users watch your own content

[Mr Lucky]

Does anyone know what query I can run that would force all users (or users of specific user group) to have these four options ticked?

Thanks

Aha, found the answer

UPDATE xf_user_option
SET creation_watch_state = 'watch_email'

UPDATE xf_user_option
SET interaction_watch_state = 'watch_email'

But, does anyone know if I can force a specific user to watch a specific thread. The above changes their p[references, but has no effect on existing threads they have started or interracted in.

Thanks
