[Suggestion]: Rename file after paste

[enkelmedia]

Thanks for a great plugin! It's real time-saver and works great!

I've noticed that I almost always rename the file and update the reference after pasting an image.

In my case, grabbing a screenshot, pasting an it and getting this:

![alt text](images/image-1.png)

Then I manually change the filename and the image name.

It would be really nice if there was a way to either rename the image (could probably be useful for any markdown-image) or if there was an option to be able to name the file before it's pasted.

I might be missing out on some feature that already exists - in that case sorry =D
