Join a game from spectate mode

Sometimes I like to click spectate instead of join game, just to see what countries are available before I decide to join--I find this easier than clicking Join, seeing you're not interested in any of the remaining countries, and backing out. However, it also means that if there's an interesting country available I've got to go all the way back to the main list of available games.

Can you set up an option to join as a country from spectate mode if that country is still available?
