You can also do it in this way:
Enter the same beamed notes twice, in Voice 1 and Voice 2.
Extend the 8th note beam inwards from either side in Voice 1 and Voice 2.
To access the Voice 2 beam handles more easily, extend the stems in Voice 1 temporarily (= while you are shortening the Voice 2 beam), by using the Beam Angle Tool:
Select the left handle, and move it up.
