Creation of a geocaching todo list

The situation:

1) In the evening, I`m preparing the geocaches that I want to do the next day(s).

2) I`m using now the "computed" flag to mark the geocaches that I definitely want to do. I know that when I`m in the neighborhood, I can get some other caches too.

3) But I don`t like to misuse the "computed" flag, because I think this will prohibit the update of these caches. Writing them on paper defeat the paperless caching thing.

So, what I want is some sort of todo-list of geocaches, sorted by me, without ruining the maps. I should be able to start the guiding to the next (or previous) cache by a press on a button. Of course, caches that are found should be automatically removed from the list.

Makes this any sense?
