Manage SD card and hard drive across Prime 4 and Prime Go

Hi, I have a prime 4 and prime go and currently use 1 SD card between both devices. I use Beatport Link and Tidal as well as local files. I now want to add a hard drive to the prime 4. My question is how do I keep both the hard drive and SD card in sync when it comes to cue points, key information etc? For example if I prepare a Beatport link track on the prime go how do I make sure the cue points are available on the prime 4? Thanks
