I'm not sure if you can "Add All" in any sense of the word. Last time I heard, the botlimit was 32 anyway.

The way I go about it is, I just bind a key for addbot and mash it to fill in empty slots (in RTCW). In ET, you can specify the minimum amount of bots to be added as whatever number you want there to be - provided your maxplayers is high enough. All you have to do is click the Fritzbot box on the bottom of the host game screen and set the numbers to your liking.
