Adjusting solids without making parametric solids

Hello,

I was wondering if it was possible to model and adjust solids in Openbuildings without making a parametric solid that keeps every step saved. I have colleagues that tend to design in Openbuildings, but keeps adjusting certain volumes, cutting here and there, pushing and pulling a bit, cutting holes, and after a while we get parametric solids with a tree of around 50 steps if not more. We get the feeling that this might make for a very heavy object, and indeed files seem to be getting rather large rather quick. We can always drop the object, but it would be easier if we had access to either non feature tools, or to a setting to automaticly drop an object after using a tool.

Thanks in advance and with kind regards,

Jeroen
