Thanks for the feedback @sledge121 - I'm feeling under a somewhat unwarranted attack here, given that I, like the vast majority of Meraki responders on here, are really only doing so largely on our own time (we have specific customers for whom we're directly responsible in our 'day job'). I was actually just thinking through some practicalities and trying to help you on the basis of understanding in the back end how some of this works:
The first point being that feature requests are, to my knowledge, not likely to be picked up directly out of such requests in the Community, given the huge volume we receive (and particularly those which don't receive a lot of "me too!" contributions) ; engaging with someone (your account team) focussed on understanding you and your business is key to the process of picking up such requests. (let me know if you need help finding the right contacts for you...)
The second being that our product development teams think very carefully about adding anything extra, not least because 'adding more' generally means, over time, complication - & we're pretty obsessed with simple. This is particularly true for adding extra steps in processes. If you can add a device type to a Network, by simply adding a serial number with that device type, that just seems easier to me. I am genuinely interested in any practical benefits of your extra step.
Anyone wanting to take forward an idea to the product team knows that they really have to gather a lot of well thought-out detail around a customer and their business and technical needs and the benefits accruing, not just for them but for other potential users. That's needed in order for any request to be prioritised over others (and we get a lot!) - to justify the time and effort in development. I've also discovered that assuming how simple something is to create is also not without its own dangers.
My intention was not to shutdown a reasonable response - you're free to add as much extra in reply as you'd like - what I was trying to articulate was that if you want to have this request delivered, you would need to be able to describe what the extra step is adding for you and the wider Meraki-using community.
