We used to be able to save presets in the Camera RAW filter. Michael Ninness did a great video that covered it at MAX in 2013 (It's right at the end of the video - about 1:05:00)
That was really useful and powerful, but I have lost touch with the changes to Camera RAW and can't see how it would done with the current version. Anyone know how and if it works nowadays? Otherwise, Actions are your friend.
