Autopano Giga allows to define the naming of the resulting panorma picture like
[Group %b]-%i_%j-%n images.pano

However I prefer another schema. Assume I have 3 photos

DSC09023.jpg
DSC09027.jpg
DSC09031.jpg

The resulting picture file name should be composed with the following rule:

1.) Start with the first (leftmost) picture name.
2.) Then add "+"
3.) Then add only the delta/difference filename part beginning from right
4.) repeat step 2.+3. for every remaining picture

So for the sample above the result name would be:

DSC0923+7+31.jpg

How can I define this in Autopano?
