permanently import .reg into .man?

I have been doing this by login script for some time now but would really
like to be able to permanently place the entries in the .reg into our
company wide .man

I cannot - because of our development department - login as the user and
then strip down the resulting .man as other entries are created which cause
corruption to one of our data entry systems

Ideally the solution would be to be able to drag and drop a .reg into a .man
via explorer
Or to be able to regedit and import into a loaded hive (and not my own
registry hive)

anyone know if either of these are possible in any way shape or form? or of
an utility that maybe allow this to be done?
