We work with a lot of multi-paging subforms. I would like to be able to pass data entered on a previous subform record, to a subsequent subform record in the same element. For example, if a user has collected 30 subform records, I would like to pass data entered on record 29, into a dynamic value on record #30. All the examples I've seen on your site only show how to reference a static record #, such as my_subform_element referencing the first subform, but there needs to be a way to to have an element dynamically reference a previous record, e.g. in record "x" be able to pull data from a field in record "x-1" (or x-5, or whatever).
