In our company we have two different brands (Brand1 and Brand 2). And each one has its own department in Zoho Desk. By default, Zoho Desk creates a portal with the URL  https://deskportal.zoho.com/portal/brand1

Now, I'm trying to create a new Help Center with the URL  https://deskportal.zoho.com/portal/brand2 but Zoho doesn't allow me to do it.

It is possible to do this? At this moment, I'm not able to create a subdomain in my company's domain.

What else can we do? Thanks for your help.
