Editing in-post links in bulk

Hi,
I’m looking for a solution to the following problem, whether it be a plugin or hack or whatever.

On my site, I have lots of in-post links to lots of different books at Indiebound.com and Amazon.com. I now have affiliate accounts with both and would like to be able to bulk edit the old links rather than fixing them one by one. Essentially, I just need to be able to add a suffix to every link that starts with https://www.indiebound.com, and something similar to Amazon.

Any thoughts?

best,
JC
