Method of scattering objects along spline

[joebain]

I've been trying to decorate the side of a track with a selection of objects. So say I have a pool of 2 (or more) different flag types I want to evenly space them and place them with some random rotation along a volume. Each spot should be a single flag, selected randomly from my set. However when using a volume spot generator it doesn't seem possible to achieve this effect, instead it will generate all the flags together, then add a space before the next group. Is this possible with a volume spot generator or do I need to try a different approach or create a custom generator?
