Clear /tell name list option

Is there a way to clear the names in my /tell history? People like to thank me for raising and supporting through /tells (instead of /say... something that's been bugging me since FFXI) but it's clogging up my reply list when I hit Alt+R. It takes forever to find the name of the person I want to /tell if it has been a while since we talked.

This is something that has been bothering me, and for the same reasons the OP mentions, I would like to ask whether the option to clear the list exists, or suggest that it be implemented, if it doesn't.
