Allow remote access to multiple site locations in Client Portal End User Accounts

Several of my clients manage multiple locations under the same company or management structure.  I have Pulseway configured to treat each location as a separate site but under the same customer.  As designed, the client remote access feature in the v9.7 client portal allows an individual login to access resources from only one site location.  This is unnecessarily restrictive.  If a customer manages multiple sites they should be allowed to access resources in all those customer locations from a single login to the client portal.  This can be done by allowing a "Shift-click" to select multiple site locations in the Pulseway web application.  Thank you.
