How to have an image inline with a selectionBox in Propertymanager

Hello,

I am writing an add-in that need a Property manager to select faces/edges etc...

My property manager have 1 selection box fore each entity type that needs to be selected.

I would like to put next to each selection box an icon representing the type of entities that should be selected (like we have in native solidworks function).

Is it possible ? I have not find how to do that in the API documentation.

I have managed to insert an icon above the selection box but not next to it.

See the "What I want" and "what I have" attached picture.
