merge or sync file

[PureMoxie]

I think it would be great if one could export a "merge" file of all changed items since the last merge import:

I'm using UR on my work desktop and a laptop at home. I've been copying the UR file back and forth via FTP. This works fine, but as my database size grows, the copying to and from my web server is taking longer. If one could save a merge file with only changed items and then import that back into the other location, the file size might be considerably smaller since only a subset of the data needs to be transported.
