Appending Exported Data With Milka Exporter



So I have been using one of Milka's exporting tools, which is amazing, but have one little question about it.

I have a lot of music and I am updating it constantly. The problem is, when using Milka's exporter, when I append new music to my old list, it creates a whole new list, instead of integrating it into the old one.

I attached a file so you can see what I am talking about it.

Anybody know what to do here?

Also, I don't know if I should even post this here, or if it should be on Milka's export development thread.

Any help would be great. Thanks

Note: It won't let me upload my I guess I can't show you.
