On LinkedIn how can move contacts that I’m in communications with and who have responded favorably, into a separate folder so I can find and access them easily?

Also, if I can do the above, can I categorize those contacts further? IE: “Attorneys”, “Realtors”, “Realtors in Tx”, “Doctors, etc, etc.

I am confused. I made the transition to Sales Navigator and now responses to connection requests are a messed up. What video is most appropriate for me to find a solution to this problem.
