How do I install the WPMU DEV Dashboard on a temporary folder

I have WPMU DEV installed on my shubrickpoint.com website. However, we are in the process of redesigning our entire website. We're doing this by having created a new website (newdesign.shubrickpoint.com) which is still under the primary domain (http://www.shubrickpoint.com. Here we will redesign our entire site (thus the url name:newdesign) and then once finished transfer it to the main domain http://www.shubrickpoint.com. Can I add the WPMU DEV Dashboard dashboard for this temporary site and if so, please give me step by step instructions.

Thank you in advance,

Alex
