I would like to be able to copy field(s) to more than one object at a time to save time in creating my object and fields structure.
For example, I decided to add a Yes/No flag to each object to indicate whether a record is Active or Not for Reporting purposes and one for Archiving. In order to put it in every object, I either have to create them manually or could use the copy feature to copy them one at a time to each object. Not a big deal if you only have a few objects, but I have quite a lot of objects.
