I use the following procedure.
In the score, in Write mode:
1
Click on the final barline in the flow.
2
This step is important. If it is not done, the score will look OK but the parts will have a rest showing at the end of the flow.
Enter a time signature as a pickup bar (eg 2/4,1).
A 2/4 bar with a 1-beat rest will appear.
3
Select either the time signature or the 1-beat rest and enter a key signature. The selected barline should now have changed to a double barline with a key signature.
4
In the extra bar (the one following the key and time signatures) select the rest in all the staves.
Open the Properties panel (lower zone) and click on Force position and duration.
[ In earlier attempts at refining this procedure, I noticed that sometimes the Force duration and position Property disappeared after clicking on it. ]
In the Edit menu, do Remove rests.
5
Open Notation Options, select the relevant flow in the Flows list on the right-hand side (it should be selected automatically, but check to be sure). In Barlines > Automatic barline at end of flow, click on No barline and Apply.
6
Select the time signature.
In the Properties panel, click on Hide time signature.
If you don’t want a bar number to appear here, change the time signature to Open (instead of hiding it). You might need to change Properties > Time signatures > Open style to None.
