I’m Jeannie, the new PM for Products & Line Items. Thanks for taking the time to share this feedback and explaining your use case. In the spirit of transparency, this is not currently on our roadmap, as our team is focused on other areas right now.
That said, I’m tracking this feedback and will revisit as priorities evolve. Please keep upvoting and sharing details in the comments. It’s been really helpful to inform the requirements for other features in the past.
+1. We have several products that each have their set of required (custom) line item properties, which may be updated during negotiations. The current default view shows too many irrelevant properties and will lead to incorrect or missing data entry. A conditional edit line item view would offer an intuitive, fast and accurate data entry process for reps.
