How to change of generated file in TeXstudio?

sometime ago I started using TeXstudio (on Windows 10). Learning of latex and its commands is not easy, but also not difficult. But still there is one thing I would like to do: generate pdf files of the same name as project, instead of main.pdf as it is in default setting.

May it be I am only blind and don’t see place where it can be set in TeXstudio. But may it be that it is needed to use another command inside tex files (mostly main.tex).

Please, tell me how to do it (how to change name of generated pdf file in TeXstudio).
