It often happens that a script or request to any database can temporarily return nothing.
I propose to give the opportunity to set the ITEM to the default value if the ITEM returns nothing or "Not Supported". If the ITEM returns nothing or "Not Supported", then the default value should be returned. This setting must be in the configuration of the ITEM itself.
Surprised that for so many years the existence of the product of this option has not appeared. It will also give the opportunity to draw graphics without voids.
