A way to designate where Jet Suited Dupes/ Flydos can fly without building walls

[PowerPowerPower]

The main limiting factor of flight in ONI is that it gets very laggy very fast. This is usually solved by putting walls up everywhere, which undercuts the advantage of using it in many cases, as the main draw is the added flexibility of them being able to reach out of the way places without the need to build infrastructure to transport dupes/ materials

 

It would be nice to have a way to quickly place down more practical barriers which would force jet suited dupes to land and walk and prevent flydo from passing at all
