Currently, if I try to export all artboards separately, the export function automatically adds "{ArtBoardName}". For example, if the filename is ABC, and the artboards are 01 and 02, then I get two files: ABC01 and ABC_02. As far as I know, we cannot customize how the file name output format is. So if I want to have the filename to be using "ABC - 01" and "ABC - 02", t hen I would have export everything and then rename them. I think it would be useful to have a way to customize how the name should be constructed.
