I have come across times where I want to mark a solution but add a caveat, or some additional step. This requires me to 1) add another reply stating what I did to solve a problem, then marking my own post as a solution (not giving credit where credit is due) or 2) Mark the correct solution then add my caveat as a new post after it, hoping someone else that may have the problem in the future will continue reading after looking at the solution.
It would be nice if when marking a solution the OP could add additional comments, or at least link from within the solution to one of their replies which may contain follow up info. Would this be useful?
