Change key of existing score

There are times when I need to change keys of existing scores due to limitations of vocalists. This was/is easy in Sibelius. Two clicks and accidentals are adjusted globally. At the moment, Dorico requires me to manually change individual accidentals after I change keys.

What am I missing?

Select All, Write > Transpose, ensure that the tickbox to transpose key signatures is ticked, click OK.

Thanks. I was looking on a different area instead of the top menu. Solved.
