Mandatory, not as in the user should be forced to use it, but the company should be forced to provide it. I was about to spend cash here until I figured it it didn't exist now I'm totally out.
I was looking for anything about this and found out that LL were apparently trying to implement it, but then I found out that was from 2009. I've hit a brick wall in my own work where I really, really need this to be a thing. Did LL give up on it?
