Automatic part transposition

Hey folks,

Need help to understand how to set automatic part transposition for instruments. Here is the scenario: As you can see from the attached screenshot the score is for Duduk in A and the guitar in concert pitch. However, I want the duduk part to be automatically transposed minor third up whenever I generate a part for the instrument without a need to do it manually. Is there a way to do it and also do it for other instruments as needed?

Thanks much in advance.
