I guess there isn't a way to do this. I'm having a hard time finding a pdf app that suits me. All I want is one that has tabs, and will remember to open pdfs at 150% zoom. Don't suggest qpdfview. It has a weird way of text selection that stinks. If it wasn't for that, qpdfview would be everything I need.
EDIT
Well, after typing the above I went back into Master PDF Editor's settings and found out that the resolution setting will do what I want. So Master PDF Editor it is for me.
