OK, if you really want, there are always ways to avoid COPY/PASTE the PAN/CROP settings to the target clips. First make a copy of your project. Next go in your original project to the clip that you want to use as the source for PASTE ATTRIBUTES and and set PAN/CROP to normal by context clickig in the PAN/CROP window and selecting RESTORE. Perform your PASTE/ATTRIBUTE to all the receiving clips. When that is done, open Vegas for a second time with the back-up project open and COPY-PASTE ATTRIBUTES the PAN/CROP settings back to the donor clip in the original project.
