It would be really helpful to be able to add lens profile corrections from the iPad directly without needing another device like a PC. For users that only have an iPad and who have lenses with profiles that are not automatically added to Lightroom, this is quite a limitation.
It would be great to be able to choose manually the selected lens profile as per the desktop version (see below). On the iPad version I am only able to see "remove chromatic abberation" and "enable lens correction" which picks the automatically selected one.
This is the last thing stopping me from switching over to iPad Lightroom full time; as someone who is shooting on unrecognised Voigtlander lenses it would be very useful to be able to manually pick. The functionality should be possible as it is already included in the Desktop version (and as I understand it the Android version)
