Importing Custom Stamps

Hi,

Is there a way to import a .PDF containing multiple custom stamps at one time?

For example, I have a .pdf file containing fifteen different proofreading marks, each appearing on a separate page. Instead of importing each image as a custom stamp one at a time, is it possible to drop that .pdf in a directory and have them installed all at once. I tried dropping the .pdf here, Adobe\Acrobat 7.0\Acrobat\plug_ins\Annotations\Stamps\ENU, or here, Adobe\Acrobat 7.0\Acrobat\plug_ins\Annotations\Stamps, but it doesn't seem to work. I am using Adobe 7 standard. Is what I'm trying impossible?

Also, is it also possible to create a custom toolbar containing those stamps?

Any enlightenment would be greatly appreciated.

Thanks.
