Allow fields from linked records to be mapped to integration fields

It would be useful to be able to map additional data from linked records when setting up integrations with my development system.

For example, when configuring the feature field mapping I may want to pass over the initiative a feature is linked to, or the Aha! Product a feature belongs to, but currently there is no way to do this beyond doing double data entry in Aha! and copying those values to custom fields.
