I was wondering if there already an established process for it before I start working on my custom solution? 

There isn’t an established process for doing this, but you’re welcome to use the API to build this for yourself.

If you manage to build something that does this, be sure to share a link to your work here in the community! I know that I’d be super interested in seeing how you do someting like this.
