What you are saying is a good feature, you may be able to rig something though, the data files are stored here:
c:\documents and settings\all users\application data\NCH Swift Sound\DialDictate\Users
Looks like the ID number is the folder name and if you open the .dat file with notepad, you will be able to see the different settings. You may be able to accomplish this with a script. But I don't see a way for it to read from a database.
