Hi
I created a QCP script that would identify the MDQ quote lines using segment key and then use segment index to sequence them and compare and verifies that the the (segment i's end date + 1 day = segment (i+1)'s start date) this way when sales rep is using custom MDQ they cant set wrong start and end dates on segments. This was covered in trailhead "Customize Your Multidimensional Quotes" it mentions below:
"Currently, editing the dates here does NOT produce a validation message if gaps or overlaps exist, even if you don’t allow nonconsecutive custom segments. If this is a concern, either remove the date fields from the layout, or create your own validation rule to check for gaps and overlaps."

To do this you need QCP script I developed
