Not a musician, but I've never heard of anything like that. I would think that if every band member did that, it would end up just causing confusion. If only the drummer did it, it might work OK, but still, many songs have different tempos in different parts, so I don't think it would be a good solution. Normally, the drummer is supposed to have a very good sense of tempo and control the tempo for the whole band. But again, I'm no pro musician.
