Allow Organization as a record relationship custom field Merged

Problem: When configuring a custom field, it is possible to select Aha! record relationships. However, Organizations (as included in the Ideas Advanced package) are not available as an option.

Use case: In our ideas portal (currently only used internally) if a user indicates that an idea comes from a client or implementation project, we would like to use a dynamic form step to allow the user to select which organization the idea comes from. As I cannot select Aha! Organization as a record relationship field, this is not possible. The only workaround would be to set up a predefined choice list, but then we need to maintain the available Organizations in two places.
