Is it possible for a drop down list value to hold a combination of Entity attributes

Is it possible for a drop down list value to hold a combination of Entity attributes

  

I have an Entity that has four values that make up the unique properties of the record.

I don't particularly want to have another attribute in the Entity that holds a combination of these four but in a list box I want to show a combination to make it a unique entry in the Drop down.


Is this possible?

Yes,


add an attribute in the aggregate, so that one will be dynamic.


So obvious when you see it written down! Blindin!! Thanks J 

As it happens I am now looking at pop ups but that's another story!!
