Member choose their own pinned thread?

[XFFA.IR Bot]

I am just wondering if anyone knows if there is an add on where members can choose what threads are pinned or highlighted for them at the top of their page or something? In case it does not get bumped for along time? Like every members can choose what threads are at top for them specifically so that when they sign in they first see the threads they choose at the top. Or if this exists but I do not know how it works?

Sorry if it is a silly idea/question. Just wondering if it exists.
