While the {image} command offers an alternative for dynamic images with URLs and the upload function allows you to insert static images, there is currently no way to paste screenshots or images using the {clipboard} command.
This functionality could be applied to use cases where content is locked behind a SSO and does not have a download option or as a quicker alternative to inserting images for snippets where the content of the image changes frequently and cannot be hardcoded into the snippet itself.
I hope you will find this feature idea as useful as I do!
