Relative Filter/Layer Presets path in Settings

It would be great to be able to set the presets path in "settings > Filter/Layer presets > path" to a relative path to the project folder, or have an option similar as "Use project path" in the History tab that defaults to the vpost folder in the project directory.

It looks like currently relative paths work, but it starts at the windows directory. If you put "." for the path and click the "recents" button, it shows all the directories in the windows folder. Just have this start at the project directory instead.
