Annoying BPM problem...

[johnnyhoney0]

This has been bothering me quite a bit since I've started to make more stepfiles.

I have to know from someone who knows what they're talking about: Is there any way to change a BPM from say...800 BPM to 200 BPM without having to sit there holding down the F7 key until you fall asleep?

I would really appreciate any help on this, because it would mean cutting down on a lot of wasted time while creating sims. It almost makes me not want to make stepfiles because I like to put BPM changes in them.
