Canon C200 Proxy Workflow Premiere Pro Windows

Recorded a project on a C200 in CRM. I also recorded internal proxy files to SD in the MXF file extention.

Now when I load the CRM footage into Premiere, "UNLINK" them, and then try to "RELINK" them to the in-camera recorded proxies, Premiere won't let me do it automatically because it doesn't "see" the file names as being the same because both the "_P" that the camera adds to the Proxy files, but also because of the file extension. Now I could't relink them all one-by-one, by hand, but I have over 300 files... not good. I could also try removing the "_P" from the Proxy file name, but that still doesn't work because of the file extension - apparently I can't get Premiere to bypass this... not good.

Any way to use the internal recorded MXF Proxy files created by the C200 in Premiere Pro on Windows? I see instructions for MAC, but I can't get windows to do it.

NOW I KNOW, that I always have the option of using "CREATE PROXIES" to create brand new proxies, but this will take FOREVER and also whats the point of recording Proxies in-camera if I can't use them?

Please help.
