"My Work" Option for Guests

I would like to create something similar to the “My Work” option for guests. My company has a number of freelancers working on various projects and we would like to have a “one stop” place where they can see everything they have due in one place without having to open up each project board. Any suggestions on how to do this? I tried with a dashboard, but then I have to subscribe all users to all the underlying boards.

There’s “My Week” which is kind of similar, but it’d a pitty if “My Work” wouldn’t be allowed for guests in the near future.
