Panasonic GH4 vlog l

Hi,

I have just upgraded my Panasonic GH4 with the latest Firmware, so now I can shoot in vlog L.

I understand, that different LUTs/vlog-Profiles are already included in the current version of fcp x. But none of them seems to really fit the footage i shoot with my camera.
Is there a way to include additional LUTs to fcp x? How can i do this?
