For some particular applications, such as Java and Python, we need to have a specific installation folder and set some custom environmental variables.
Python has this setting as a checkmark when you install after downloading from its website, so there is some parameter that is triggered.
For Java, if you use an additional argument you can already do it, but using a dedicated field would bring improvement for all other applications that could needs this change.
