@Skematica nope not like that, Apero on the Mac has that option. I did make this app FileZ for Pnut by Yellow Dice https://itunes.apple.com/nl/app/filez-for-pnut/id1286623843?l=en&mt=8 where you can see and manage all your files on pnut.
Check the original post in this thread for a Siri shortcut example on iOS 12 in combination with ChimPnut.
ChimPnut update 1.5.3 now available in AppStore. This version improve Siri search functionality. This is also interesting if you are already have iOS 12 on your device and use Siri shortcuts.
