Franchise in Similar Games

I'm not sure this has been handled before, but I was wondering if it would be possible (or IF it is possible) to add an entire franchise to the "Similar Games" section. Say, if a game is similar to the Final Fantasy games, I would like to add the entire franchise, not go through the whole list of games and add every single one... or is this a foolish idea thinking that, for example, the Final Fantasy franchise has a few more releases than just the standard JRPG (like the tactics games). I'm not sure if I just answered my own question and shot myself in the metaphysical foot, but I feel that the community should consider this.

In that case, I try to think of one or two games in the franchise that the game is most similar to. Having an entire franchise listed annoys me quite a bit.
