I don’t know, and I have very limited working with pref, but what do you want to make, i.e. is it complicated.
My experience with pref in BB view is that there isn’t enough part drawings in BB view to make a perfect sketch.
Like the BB view of a resistor is 400mil, and in real life you can make ¼W 300mil, but to do it in BB view you have to use the bendable legs fit 300mil and place the resistor to the side. If the sketch isn’t complicated and you have lots of room it should be ok.
The next problem is making a pref. I don’t know how to do a custom one so I tried to make your board with small sections of pref from the Bin, but it won’t allow 1 row horiz boards.
PCB view is accurate real life, so in theory you could make a custom pref with via’s set on a 100mil grid, but that would be a last resort if no one knows how to do the BB pref.
NOTE pref = stripboard
Damn, I just remembered you can click between holes to make or break tracks so that you can make that board
