Mixed meters

I often write songs and hymns. They often have an uneven meter meaning the bars don't always contain the same number beats. It may e.g. be a mixture of 4/4 and 5/4, 3/2 and 2/2 or the like. You usually won't set a new meter sign in every bar but start the line with both meters (e.g. 2/2 3/2). It's no problem for me to change the number of beats inside a bar, but I can't find out how to set multiple meter signs in the beginning of a song.
Is there a way to add a second meter sign to an existing meter sign?
