Zooming pages

I use Musescore to write out scores for folk dance tunes. I would find it very helpful to be able to zoom pages to a size where the score fills the screen, not the page. This tends to be somewhere between 100% and 150%, but there does not appear to be anything between the two. 100% is too small to read comfortably and 150% is too large to fit some tunes on the screen. Is there any way of customising the zoom settings to allow me to zoom to, say, 120 or 130%?

This is only a problem on my desktop PC, which does not have a touch screen. Resizing on a tablet can be done to the size I want using thumb and index finger.
