You can force a view title on a sheet to be multi-lined.
In the properties of the view you want to change, under Identity Data, go to Title on Sheet.
Type your view name and when you want your next line Ctrl+Enter adds the hard return to text.
Now the title on the sheet will be multi-lined:
Note that if you pick the black triangle on right of Title on Sheet each line is listed as a separate choice.
But you can only select one line from this list. So if do that you will loose all but one line of your title.
