Yes I am specifically after .msp file types, as we woild like to block end users from downloading and installing .msp files. This is not on the list of supported files currently.
If it is binary file you might try hex editor to get binary signature from beginning of file and create your own vulnerability signature.
MSP files are currently detected under the Microsoft MSOFFICE file type, ID 52033 (at least that's how they're detected when passed through my firewall in my environment).
If blocking that causes you other issues, then I would recommend talking with your Palo Alto Networks SE to see if .MSP can be either combined with .MSI, or broken out on its own.
