Add pull-down for multi-switch nodes

Instead of naming the Input as A or B, this can be changed at the user's discretion

A -> Type A, chair (with backrest)

B -> Type B, chair (without backrest)

The pull-down menu will then also display the changed name Changing the pull-down is used as a switch

Sometimes it can be difficult to understand using only integers, so this is very useful to avoid this

Modifier Properties should also be able to display this pull-down menu
