Qsync can’t do one-way sync?

Hi, is it possible to manage different sync between PC and NAS?


PC folders “ABC” -> [one way] to NAS folder "ABC"

NAS folder "XYZ" -> [one way] to PC folder "XYZ"

In Qsync I only see bidirectional sync, and Politic is unique for all folders (so I'm not able to define priority between PC and NAS files for every sync) If not, could you suggest a good software to do this?
