Photoshop: export layers to files adding group-name as prefix - photoshop-script

Question

I need to save hundreds layers as jpg files from a given psd.
Leyers are grouped in several groups and every group's name should compare as the prefix in the jpg's files.
Group1
|
layer1
|
layer2
|
layer3
Group2
|
layer1
|
layer2
I need something like this:
Group1-layer1.jpg
Group1-layer2.jpg
Group1-layer3.jpg
Group2-layer1.jpg
Group2-layer2.jpg
I found many .jsx scripts that merge and export groups but can't find anything according to my needs. Does anyone know how to do that?
thank you
