Is it possible to insert the gist_id into the magic call when creating a new snippet/preset?

[pramukta]

As it stands, when posting a new snippet, we run something like %%gist with no parameters. It outputs the gist id and then we often copy and paste that id onto the magic invocation line (%%gist <newly_created_id>). It would be much nicer if that was just automatic. Otherwise accidentally rerunning the cell would create yet another gist.
