Its not that silly. Its actually the way it's meant to be.

The only part that you missed is that you should trigger the same builder,
but with a different property. You can then use canStartBuild (
http://docs.buildbot.net/0.8.10/manual/cfg-builders.html?highlight=canStartBuild#builder-configuration),
in order to select which slave will take the build.

Now, how can you trigger the same builder with different property in one
Trigger step.
If you are on eight, then the only solution is to create a lot of
Triggereable schedulers with different set_properties options

If you are one of the happy early nine adopters, then you can use the new
Trigger step customization point:
http://docs.buildbot.net/latest/manual/cfg-buildsteps.html#buildbot.steps.source.getSchedulersAndProperties

HTH,
Pierre
