How do I display the transposing instruments as transposing in the full score?

So, I am creating a Trumpet Solo, accompanied by Piano. The Person I hope would perform it, might read the full score as is. I want the Trumpet Staff to display in the transposed pitch, instead of concert pitch. How do I accomplish that?

Edit --> Transposed Pitch.

Elwin, when you view and print the trumpet part layout, you will find that it is already in transposed pitch by default.
