Delay PlexMS launch for RAMDISK initialization?

I'm trying to configure Plex MX (Windows) to use a RAMDISK for transcoding. The RAMDISK is created using Windows Scheduler. The problem is that Plex MS starts up too quickly and tries to find the RAMDISK which isn't initialized yet and throws an error:
Error creating directory M:: boost::filesystem::create_directories: The system cannot find the path specified: "M:"
How do I get PlexMS to delay launching to make time to find the RAMDISK after its initialized? Frankly I'm not sure how anyone managed to accomplish getting PlexMS to use a RAMDISK given this race condition.
