LGTM, could you just add a test working with ids instead of names ?

Hi @gmalinve ,

Named selections is the old ¨Lists¨ in AEDT. Please review first the class Lists in modeler.

Prabably it is still valid, but you could transition to NamedSelections because it seems the future. In addition, this feature is available from recent versions so this should be also controlled.
