Limiting/blocking texting to certain contacts without blocking contact all together or limiting the hours to allow texts.

Certain contacts I do not want texting from due to the sensitivity of the topic. Also as an professional, I do not want to be held responsible for failure to respond to texts especially off hours. I want to be able to either limit who can text or limit the time/hours to receive them. To be able to toggle and enable and disable texting as well as schedule when texting is allowed or not allowed.
