[Automatic lens correction with fully manual lenses?]

Howdy, new user - very impressed so far.

I'm wondering if there is a way to use a fully manual lens - like the Samyang 8mm f/2.8 UMC Fish-eye, with the automatic correction profile.  Or at least a way to apply the profile manually (much better solution for me (as I have lots of manual lenses).

The lens IS the supported list of lenses in the lensfun database (pulling through the forums this appears to be the one you use)

http://lensfun.sourceforge.net/lenslist/

The problem is - for any of these manual lenses - the lens data is not reported to exif so it's not automagically applied.

Thanks for any help.
