It is not hard to change the default compilation engine in TeXstudio from PDFLaTeX to LuaLaTeX (or any other engine for that matter). But if I only want to use LuaLaTeX for a single document, it gets tedious to go into the menus and find the LuaLaTeX option all the time. And the command line approach is also more time-consuming.
Is there some clever way to tell TeXstudio to always compile this (and only this) document using LuaLaTeX?
