The import process is "do whatever it tells you to" under XData Tab, while exercising the few options available to you. If, before importing a database, the user creates a bunch of extra data fields, such as Lat and Lon, then, usually, those data fields can be exported back out as text (csv or other) files. That is the only way that I know to get Lat/Lon fields exported except by GPX files from draw (routing?) layers.
The XData routing process I added in the last paragraph above as an afterthought, probably while you were replying to my original post. It is extremely simple to implement, but maybe not intuitive.
