how to display tied notes as single notes

There are many places where I’m finding Dorico insists on displaying whole notes or half notes as multiple tied quarter notes. This happens when I have other quarter notes in the same measure. For example, see this example… how can I have it so that it shows the bottom note (the B natural) as a single whole-note? Is the only way to do this to assign that note to a separate voice?

Use multiple voices.
