Change underscore to dash when exporting artboards
Is there a way to change which character is being appended when exporting artboards? I can't seem to find anything in the preferences to do this. Currently, AI is automatically adding an underscore + the artboard name. But rather than an underscore I would like to use a dash.
As an example, say I have a file named: icons.ai
There are a variety of artboards in this file. And currently, when exporting them, they use an underscore: icons_artboard01.png
However, I would like them to use a dash instead: icons-artboard01.png
Does anyone know how do do this? Currently I'm having to change them after the fact by hand, which becomes extremely tedious when you are dealing with a large number of icons.
Additional info: Adobe Illustrator CS6, Mac.
