Questions about TAG's

[CatWeazel67]

Hi,

I'm trying to restrict what one user can see, so I thought I could just TAG the shows they want.

I expected that if I tagged a show then all seasons and episodes for that show would inherit the same tag, but that doesn't seem to be the case. For something to show up for the user I have to tag all the actual episodes. 

Is this expected behaviour or am I missing something?

This also raises the problem of how to tag new episodes automatically?

Thanks
