Adding a measure to a score

I am used to Crescendo. Trying Dorico. But can’t find an easy way to add a measure at the start of a piece where the Midi file has not shown the first few rests

select the point to insert bars, and click “shift + B” and type in the numbers of bars you want, then “enter”.

If the pickup measure is not a full measure, re-enter the time signature with the appropriate number of beats after a comma (based on the denominator of the meter). If in 4/4 and you need a two-quarter note pickup, type Shift+M, “4/4,2” [Enter]. If you need an eighth note and a quarter note, type Shift+M “4/4,1.5” [Enter].
