Referencing maps in Atoll

[algilsan]

I have all strm maps of my country. I would like to manage all files in atoll, but since there are files in differents UTM zones, i don't know how to do it. In Global Mapper i can open all files at a time, and everything is well referenced

I can import all files in Vertical mapper file, but when i have to chose an UTM zone, all repeaters are not well referended, because when i export them to googgle earth (with google earth plugging), their position is not correct

What's the problem?

Regards
