How to transfer save files between 2 ps4 consoles?

I often jump between 2 ps4 consoles in the same house both have bl3 downloaded to them. This worked easy with all previous Bordlerlands games but I cant find a way to do it on BL3. Tried upload save game data and re downloading on 2nd PS4 and it wiped another save file of a different character.
How can I transfer my saved games between consoles?

I recommend a flash drive I move my save around alot just make sure you dont overwrite the wrong save when doing so also this is a great way to back up saves incase you accidentally corrupt your data
