CLIENT PORTAL ON MULTISITE WORDPRESS

Hi,
I created a multi-site WordPress site dedicated to the tenant of a supermarket.

Each tenant issues global invoices (every weekend) to customers through a website.

I used WordPress multi site, with client portal and profil builder

Result:
Customers can retrieve their invoices via the link: http://www.domain_name.com/tenant_name using the client portal and profil builder plugins

Question:

Is there a possibility that customers can get their invoices via http://www.domain_name.com link by entering the username and password as via the link http://www.domain_name.com/tenant_name ?

thank you
