I'm trying to replace mac2imgur with an equivalent tool that will automatically upload a screenshot taken in any way on macOS.

Katana doesn't seem to look for any new screenshot that is saved to the screenshots directory and upload it. Instead it offers one shortcut that can be configured.

I've changed macOS's default "select part of screen" command+shift+4 shortcut to something else so I can set it in Katana settings (not sure why it says space):

Now when I use command+shift+4 and select a part of the screen, it instantly uploads to Imgur without showing the macOS screenshot editor for annotating before upload.

Is it possible to only trigger the upload after the screenshot has been edited, like mac2imgur's behaviour?

Better yet, I'd prefer to use all of macOS's default screenshot shortcuts (capture window, capture screen etc.) with Katana just handling the upload part.
