Is there any non-destructive way of designing?

Hello, I'm looking to get into MOI3D, used trial version for a bit, but what really draws me back from purchase is seemingly no way of altering the objects one the action has been completed. For example, changing the champhered edges profile without having to delete and re-build it from scratch.
Is this really the case? Was this feature really not needed? Will such features ever be considered and implemented? Thank you.
