What I'm looking for is something that let's you pick a specific sprite when chaging an event's image. Back in RPG Maker XP, when you used the change image option while messing with movement routes, you could pick any individual image for a sprite to change the event's appearance to. MV only lets you pick the 3x4 set of images that make up an entire sprite, and by default it will retain whatever direction it was facing.
Basically, I'd like some way to have an option like this:

that appears in the middle of an event, rather than having to use this:

If there could also be an option to make that event retain it's changed appearance even after you leave a map, like how Yanfly's Save Event Location plugin tracks retains the position of an event that moved after you leave the map, that would be amazing.
