Update parameter

Hi there,

I don't use the PortableAppsPlatform for anything except to quickly and easily update all the apps (I use a launcher I wrote myself using Autohotkey). I was wondering if there is a parameter or another way to only update all the installed portable apps and then auto-close?
You're not supposed to PortableAppsUpdater directly, I tried that

Thanks in advance!

PS. if you're interested in the launcher, let me know, it's on Github.
