Has anyone found a way to batch convert csv files (mine are exported from GSAK for geocaching) to mmo files?

At the moment I have to go into MM, inport the csv as overlay and then export the overlay as mmo. Whilst this works fine for a single file I have an automated process which creates several different csv files at once.

The top of the csv file is and the first 2 waypoint records are:-

The top section related to icons can, I think, be deleted as MM alredy knows them from previous imports.
The 4th value in each record is the number of the icon. The last but one value is the category type in the overlay.

Thanks
