[Etoys] Testing when a morph is dropped in another morph

[Hilaire Fernandes]

>From Etoys is there a way to check when a Morph is dropped in another
Morph to later take appropriate action?
Moreover when doing the check I would want to decide to accept or not the drop.
Is it doable with Etoys tiles?
After a 30 mins research,  I have failed to see how it can be done.
