Deriving a group from a group in Global Data

questions
1

In code I can derive a group from a group and then extended it:

ProductEntity:Simple GROUP,TYPE
productID LONG
productName STRING(255)
barcode STRING(50)
END

ProductEntity:Extended GROUP(ProductEntity:Simple),TYPE
productDescription STRING(1024)
imageURL STRING(255)
netWeight DECIMAL(10,2)
END

I want to do the same but in the Global Data, but can’t see how to do it in the UI? I can create the first group and set as a TYPE, but can’t see how to create the 2nd as the Simple class does not appear in the Derived from, is this not possible in the Global Data?

SOLVED:

Solution is to type the derived from GROUP into the Base Type field, it does not appear in the select window, but you can type it in.
