PortableApps Plattform LastMonitor per Machine

Hi, since the last plattform update the menu opens on the correct monitor on one machine, but on the wrong on another. I investigated and found, that the LastMonitor setting is shared between machines. If there are differences with the amount of monitors or just their numbering of the graphics card this will open the menu on an unwanted screen.
Would it be possible to change this setting per machine, so it remembers the correct monitor for each one, or alternatively a possibility to disable this setting?
