Currently, during designing Interact forms we could choose one field as Key Value, which is displayed in general Submissions tables (as Submission History), without viewing submission details. But we couldn't modify Key Value during BP process.
It would be very helpful, if we could assign some field (or fields) during form designing to be displayed in general Submissions tables (as Key value) and could be modify during BP process from BP action "Edit Form Field". It could be use e.g. for updating current status of BP process, easily visible, without going into sumbmission's detail.
