Add link for Issues to top of Customer form

At the top of the customer form are links to:

Sales Order
Delivery Note
Sales Invoice

How can I add a link to this list that will take me to Issues for the customer?

It will have to be added in the product for now.

See customer.js in erpnext for clues.

I have added the button on the view and make option without issue and it works great. I tried to add a badge for issues to show me how many are open for the customer just like the sales invoices and opportunites but where the number is supposed to be beside it, it just shows “-”. How can i fix that?
