I don't think so, if you're talking about doing it in an automated way. For the csv its easy to count rows, then minus one for the header to get your total. Are you able to export, count, add that in at the top and then send to your management?
If not, you may need to inquire about a custom report solution. I don't know much about doing this. They are created as jsp files if I'm not mistaken. The Resource Kit has some examples you can examine, but I don't think it really explains how to create them. JAMF can also help with this, but perhaps not for free. Someone here may also have experience in writing custom reports.
