Lead sheet help

I'm creating a lead sheet of chords and lyrics. In one section, there is an a capella voice singing over a drone. The drone goes for many, many measures and I don't want to type in whole note after whole note when I can just tell the performer to play that throughout the section. I'm having trouble attaching more than one word to the whole measure rest symbol and I'd prefer not to configure each note of the song. This is pop music, not classical. Is there a way to easily put in the lyrics without attaching them to notes?
