Combining trombone 2 and 3 in one part

I will combinate trombone 2 and 3 in one part as trombone 2-3. Now I copy part trb 3 to 2. Is there a better way with condensing to do this? This is not the score but the players part.

You can enable condensing in any layout, including in part layouts, so if you have 2 separate trombone players already you can include them both in the same layout and then enable condensing if you wish.

Thanks! The step to combinate them first is the trick.
