Add tag for "games without plugin data" ?

[elreymu]

Since there's no tag for games that have no howlongtobeat information they are scattered all over the other tags in playnite, making them hard to find. Would like to filter the games that have no data with a tag.

I know there's a way to see the list of games, but would be nice to be able to add a tag for them to be able to easily find them in one place.
