I’d love to know who uses LinkedIn Talent Hub?

At SSW we moved over to LinkedIn for our recruitment system (aka ATS being Applicant Tracking System) and it has been a good move, although it is much more $ expensive.

I find it annoying that there is no field to keep track of someone’s salary expectations.  Currently I write it in a note: 

How do you keep track of candidate’s salary expectations? What is the logic of not having this important field?
