Jarty,
if you are still struggling, I've made a little useful loop for myself, which reenters all the list's items in it, so that I could save default values as well.
If you build yourself smth like this, you can just delete a current encounters GA, create new, import text from file, and then just run this loop while saving (actually, at least once, this may not be every time you save).
So, my example:
I have list GAs: "top.names" and "top.points" - and also a text attribute "buf.txt".
On every loop step the buf.txt is assigned one of the list's item and then this very item is replaced with the content of buf.txt (which is similar, yet now it is entered with behavior, so it can be saved).
Ask me if something stays unclear in this.
