P: Edit EXIF data

I would like to have the possibility to edit EXIF data in Lightroom CC. 

For example the data for the used lens and the used camera.

Currently it is only possible to edit the data of the file.

This would be very usefull, when you e.g. import scans from fotos that were taken with an analogue camera.

Or if you import pictures that were taken with a lens, that does not report its type (like when you are using adapted vintage lenses)

I currently I use an external software (EXIF Editor), and import the pictures afterwards.

This is (I think) possible in Lightroom Classic, but not in Lightroom CC Desktop
