subscription update a test area

Hi there I have Hikashop business and it says my subscription is tied to my website, I am developing a new site to replace my old one in a area under the main site called test (spookily!) but I cant automatically update it as the updater tells me its not tied to the site. Is there a way for the subscription to be tied to a test area for testing as well. I know I can manually update but its another stage..

of course, as its only for updates, I will switch on my brain today, thank you !
