Multiple HHD's & VST Sample Content

Hi Guy’s

I’m about to setup a new system with multiple HHD’s, to create seperation between programs (Cubase 6.5 & HAlion 4)
However, I don’t recall seeing this option (Sample location) when I installed HAlion 4 on my current system.

Does anyone know if this is possible durinf the install?
If not is it possible to do during install, do you move the sample content after the install?
