Hello,
I liked the idea of your suggestion, and I don’t know if Trimble will respond favorably.
In the meantime, here is my proposal via my plugin SJ SectionBox.
I hope it will meet your expectations.
I remain open to any suggestions for improvements, within the limits of my skills
Thank you for your feedback
