The reason I mentioned that Umbrella supports it is because Cisco positions Umbrella as an addition to Meraki gear as a suite of products.
Having previously worked closely with development teams at a vendor, small changes like that are often the hardest to get across the line because they cost too much to implement for the value they provide.
When you factor in taking devs off other critical bugs to do the implementation, testing, validation, documentation/training and support, it comes to multiple thousands of dollars.
That's why it's often up to the sales team to justify why this is important for customers in terms of deal sizes and $$
