When Exporting a Microsoft project to Excell, project groups multiple successors into a single cell. When mapping values during Yed import, it would be helpfull to recognize (maybe by an option check box) that the Column of Target IDs includeds comma separated Target IDs.
The only alternative i've found is to manualy separate the lines and copy all other info to a separate line to identify the separate column ids. this can be time consuming in a large project with multiple Target IDs for each Source ID.
