yes this is possible, here is the snippet of code that makes the labelled arrows in LRP. (see http://pleiad.cl/LRP for a picture ;-) ). You need to set the model, and then do a @ RTLabelled

edge := (RTEdge from: efrom to: eto) model: trans name.

arrow := RTArrow new color: trans color.

arrow line width: 2.

arrow head width: 2.

arrow withOffsetIfMultiple.

view add: ((edge + arrow) @ (RTLabelled new color: trans color; view: view; offsetOnEdge: 0.3)).
