Bust the dust issue

I have  the Bust the dust kit and have noticed an issue.

Dust is collecting on the floor in inaccessible areas which sims can't reach such as up in castle towers. Places which naturally don't have any entrance to get access to cleaning the same. This makes it necessary to pause the game and remove the dust by deleting each pile in build mode.

Is it possible to make dust collect only in areas which have a door or door opening?
