Is it possible to upload a file to Dropbox and have Monday create an item with the file attached

Is the below currently possible?

I want to have clients upload a filled out PDF to a Dropbox folder, then have Monday create a new item when this happens AND have the same PDF attached to the newly created Monday item.

Doesn’t have to be Dropbox. I’m agnostic to what the platform is. Also happy to use another application, like Zapier, if it’d help.
