Set modified date - use "Set from file" as default?

Maybe a minor tweak?
Attributes change - set modified date - pre-fill date-time "Set from file" as default.
After all, that is the date-time stamp to be changed (seems more logical)
Also if, for instance, only the day should be changed, one is not required to enter full date and time.

We'll add a way to do that in the next update.

Thanks a lot!
