P,
Sorry, there was no “silver bullet” at the time. I have not revisited this. I’m sure it is possible in the C++, as far as using UE4’s graphic user interface I thought up ways to add to the content browser within or use a server. Neither were/are worth my effort at this time. I’ll likely revisit this at some point, but at the moment I’ve moved onto a different project.
I do get the feeling since this post, Epic Inc has made some promising improvements to their engine’s capabilities, but I do not believe this was one of them yet.
Keep on keeping on,
