How to bind a Crew Member to a bed

I made a Captain room in my ship and it makes me a little bit angry that the crewmembers can walk around in all of your ship and can sleep everywhere. So my question is: Is there any way to bind them to a bed or to say from which room they have to stay away?

 

This perhaps?

 

xD thanks alot...

 

Binding crew members to a bed... kinky...

Anyway, it might be possible to lock them into cells you build around them, but i wouldent be suprised if they could glitch out of it if you leave the ship and come back.

 

Use switched doors, and put the keypad out of reach... Or just use a combination lock keypad.
