Can Status plugin download images from external URI's?

When the Status plugin inserts an image into a post, it actually just links to the external image URL.

Can be changed so that it actually downloads the image, places it in the local media library, and then links to the local image?

It would be nice to know that the image I intend to show in my post can’t be later removed or changed by someone, who could theoretically just replace the linked image with a different image of the same filename.

Thank you.
