Is there a hack that allows user to mark an individual post as read when THEY choose?

Is there a hack that allows a 3.6.5 user to mark an individual post as read when THEY choose?

I brought my userbase to vbulletin cuz we all know it is _very_ cool.

However, I have not been able to find a hack that allows a logged in user to control when they want to mark any single post as read.

Seems the default for vB is if a post hits your screen once, it's automatically down the memory hole after that.

I'd sure like to have a solution to this. My users are chewing nails.

Thanks!
