External Links form SD+

Hello, we are evaluating SD+ and i miss a function do define a external link for custumers to show or integrate important informations from our erp system (like billing informations, account statements, etc.).

To solve this question we need to make individual fields to the customers. these informations should not be editable for the customers (customer no., etc.).
Then we need to define the customer main menu, to integrate functions like display account informations, etc.

Is a solution in your roadmap to solve this requirements or is there already a way to fix this requirements ?

many thanks for your informations.
