Default vertical zoom setting

This may seem minor, and I agree it is, but I'm frustrated that I have to resize my zoom level every time I open the project. I like to scale the tracks down to just small enough that I can see as much of the playlist as possible but still see the "thumbnail" of the waveform and piano roll notes. Not a big deal, but it changes back to default automatically. Is there any way to change this default setting to a custom size? If not I will just cry myself to sleep and move on, thanks.
