Ability to add menu items to customer facing portal

We’d like the ability to add menu items to the customer facing portal

We use Zendesk for support in our biz so don’t use the inbuilt upmind ticket system. We’ve had a number of customers ask where the helpdesk is when poking around the backend

There’s also some marketing related menus we’d like to add such as free tools and free reports which we can’t add right
