Batchmode converting jpegs to orux maps

Hi,

I have a rather special problem: several dozens of old scans of maps in various scales without any georeferencing information that I could use conveniently.

I have imagined I would convert the jpegs to oruxmaps format leaving georeferencing blank - and once I am in the area where I need one of those maps I would load it into Oruxmap and calibrate.

Now my special question, can I somehow batchmode convert all jpegs in a directory to oruxmaps leaving them without georeferencing information to calibrate later?

Thanks for any ideas
