Is it possible to cycle different lengths on different tracks e.g. one cycles on 4 bars one on 2 bars??

Using Garage band in a live situation, is it possible to have the different tracks cycle at different lengths?

e.g. You only need to play one bar of the drums as its the same through out, but you need to play eight bars of bass guitar to cover the loop.

So you have the cycle length at 8 bars to cover the bass... is there a way round, in a live situation (so not cut and paste) having the one bar of drums cycle or auto fill the unused cycle length
