Allow dynamic objects to be created without a target URL

As of today, users are required to specify a target URL in a dynamic object. For example: www.orders.com/orders/[ORDER ID]

However, not all business objects can be linked to through some URL. Some business objects live in desktop apps or aren't easily identifiable via URL. In these cases, it would still be useful to build a dynamic object with custom fields that levarage an API.

Suggested feature: Allow users to configure a dynamic object that doesn't require a target URL
