How to install Logic Pro X additional files to a secondary hard drive?

Hi all, I have tried and failed to install additional Logic Pro X data to my second hard drive. The SSD that OS X runs through is almost full and I don't have enough space for the files to stay there.

I have tried to use the 'Symbolic Link' solution, but to no avail as it continues to install the software on my SSD! I can tell, because after installing the files I lose a big chunk of storage on the SSD.

Please help! Is there an alternate solution, am I doing it wrong?
