use main website subdomain for the Module demo and Information

Hello,
For first time we want to upload our script to CodeCanyon,
i just recognize one point that all the script added , are using Spacific & separate website url just for that item.
may i know if we could use our main website (Software development) and use the sub-domain for Application which we want to offer in CodeCanyon?
or its not fit CodeCanyon Policy?!
