Editing Comments? (Especially those that are not completely accurate)

Is there a way to edit pre-loaded comments?  For example, the Run-on comment says to add a period or a semicolon.  However, there are two other ways to fix CS and RO's , and I would like my students to have all 4.

  • I've ended up recreating those comments that were incorrect, and then using my own. It is an annoyance, however.
