I know somone that gets around this by putting a bunch of objects in the same project as separate chunks so that it is easier to manage in the short term, but it always felt like a bit too much trouble for me. -- this was a few years back.
if using pro: You could also bodge the network processing system to do something similar with everything running localy, but that's even more trouble if you arn't already doing network processing. Bit of a learning curve.
