is there a way to export xml from "database" area?

[crump]

for example I am a fan of Temco. I want my all temco games from Mame romset to another folder.

in "database", I can sort titles by Manufacturer, and I can select these titles, but there's no way to export these imformation to xml for me to rebuild, right click does nothing; or in "Rom Files", there's no sort by Manufacturer, the manufacturer colum is just simply not there, I can't sort games here this way and copy to another location.

Is there anyway to do this? Thank you.
