Mike, if you have to add specific usage rights on a regular basis then I suggest that you save the new pad, with all the other fields unchecked, as a snapshot.
With a little thought you can even title the snapshot so that it stays below more regularly used ones.
You can even add snapshots for specific clients or types of use. I find these save me time when I have to create a folder from a job for a regular client who I am allowing different usage rights as I can then just select the images, open the IPTC Stationary pad, select the relevant T&C's and apply.
