Candidates' Linkedin URL

Candidates' Linkedin URL

1. 
I add a candidate's Linkedin URL to a field I designate for that purpose.   I prefer it as a field (instead of the button next to twitter etc)  I can search or view it or search buy it more easily.  I also import a lot of csv files including this Linkedin url.

2.
When I parse a resume it adds the Linkedin profile to the Linkedin button.  Nice when I'm browsing candidates but not a field I can work with like #1.

So now,  I have Linkedin profiles ()  in 2 places..  Is there any way (perhaps a custom script yikes) that I can add all the Linkedin profiles to my other (real) Linkedin field?

Or is there another way to do that?

Linkedin and how we use it is a critical part of our ATS

Thanks,
Philip
