Is it possible to create own categories in the plane selection menu?

ui_typerole=“Single Engine Prop” ui_typerole=“Single Engine TurboProp”
ui_typerole=“Twin Engine Prop” ui_typerole=“Twin Engine TurboProp”
ui_typerole=“Single Engine Jet” ui_typerole=“Twin Engine Jet” ui_typerole =
“Commercial Airliner” ui_typerole = “Rotocraft” Are there additional keywords
for “ui_typerole” ? Is it possible to create own categories in the plane
selection menu? ui_typerole = “Helicopter” → will go into category
“HELICOPTER” instead of “OTHERS” ui_typerole = “Ultralight” → will go into
category “ULTRALIGHT” instead of “OTHERS” Is that possible?
