Digitally Stamping an Attachment

I am looking to see if anyone has come up with a creative way to digitally stamp an attachment without having to download, open, stamp, save, and upload said attachment.

We have an approval process that goes through multiple steps and the final step is a stamp. This is a timely process and I am looking for suggestions that folks might be using.

The stamp has to have a red box around it and has customized verbiage with each attachment. I tried with proofs but there are not enough annotation tools.

Thanks!
