How to NOT let the user Select All in an Enumilst?

[Julien]

Hi there,

I use an EnumList type in a field of an app related to safety.
Since it is related to safety, I cannot let the user Select All the items from the EnumList, if the user is lazy he might do that without thinking of his own safety…
So I want the user to carefully consider each items of the list.
Is that possible?

Thanks !
