Add more option in "reference model" in display mode

Detailed description of your suggestion

Hello, I have a spear and in minecraft, I use UseAction.SPEAR to display it as being throw when player hold the right click, but I don't have the option in block bench so it's not easy to determine which value is the right position, so "basically" I wanted to have more options than charged bow and crossbow,
I know this is a lot of repetitive work to support it, I can do it right now, but having this option will be very useful
