A way to see how long a prisoner have been in restrains.

[Evul]

I whant to a way to see how long a prisoner have been in restrains.
Suggestive under the prison tab. Cause at the moment i am managing some kind of Military Colony, and i have a prisoner in the prison that have been there the entire time the prison have existed with one escape attempt due to raiders. But yeah some way to determent the time the prisoner have been in restrings would be nice
