Is there any way to add subform data from Zoho Forms into a merge template? None of the subform fields are in the "manage fields" section. If I click the gear icon, I can see the subform is mapped, but there is no way for me to insert anything into the template. It's very frustrating, the data source is a Zoho Form and for some reason it doesn't offer the "Subforms" section right next to the "Main Fields" section (see screenshot) like a CRM source. I'm beginning to wonder why subforms exist since there is always a problem working with the data.
