Usability of Slates in MC Education

I would like to suggest adding slates as block or entity in game, so it can be summonable/placed by commands in game.

Currently, what I saw in my developer experience that scripting is very commonly used these days. And personally I see lack of possibilities with items like slates, camera or portfolio, because they are not fully configurable in the files and without extensive knowledge of JSON there is no possibility to change anything. 

So, the main request from me would be to add more configurability to these items, especially - boards/slates. When we create map fully with commands etc. placing boards by hand is exhausting and counter-productive. Please consider it as feature which will really help people who are creating maps from scratch.

Greetings!
