It is possible to transfer all the macro from my PC to PS4 later?

Since we can already share account. For someone who move back and front between PS4 and PC often. I want to be able to upload my macro from PC to somewhere that when I get back to PS4 then I don't need to make a new one.

I know that you can do this back up between PC to PC now. But I want to ask for PS4 option too! Is PS4 dev team trying to work on something like this?

Unfortunately they have said in many places that it is currently impossible. They would have to do tons of server overhauling to create a dedicated server on their end, and any other method violates PSN file sharing agreements. So for the time being it is impossible, but in the future at some point they may look into it again.
