New button on Dealer - Contact related information

CRMOD Admin question.

I am configuring the Dealer object in order to be able to use the object for our organization.

On the Contact related infomation section I see one button available which is "Add" (a contact).

I am missing the "New" button with which the user can create a new Contact from this related information section.

So what I need is the ability to create a new contact from the Dealer related information section the same way as we do this on the Account object.

The user that I'm testing with has all the relevant setting enabled (I think), like "Can create" on the Contact object and Read/Create on the Contact related information with Dealer in the associated Access Profile.
