Hi Jessie, I know we're looking at revamping the reporting system, but I do not have an ETA on when that will happen. That said, you could book some time with our consulting team to explore options, or if you're comfortable with text mode, you should be able to reference a collections for the task assignments. Here's a help article that discusses how to use collections in reports:

I'm around a 6/10 here, which is why I recommend our consulting team. You can contact your Account Executive for a quote for a small block of hours. Thanks and good luck!
