Would it be possible to, when saving a new or old flight plan, to present a list of whatever flight plans are already saved?  Including the date the flight plans were last saved would be helpful as well.  When designing a flight plan I may forget whether or not I already saved it.  I may formulate a flight plan to a location that I did a month or more ago, and the default, or obvious name may mimic the old one.  It would be a bit easier if, when I went to save, I'd see the old, like named plan, with the earlier date.  I may want to save both as each has specific reasons for the route planned.
