How to track multiple events?

Hi all! I am trying to create a multiple events tracking system in my bubble.io app, how do I do it?

For example, if a user wants to track their activities like Work Hours, but also want to track another activity at the same time, how would it work?

In my present app, I am using this plugin : Timer / Stopwatch / Countdown Plugin | Bubble but it allows me to track only one event at a time.

Thanks!
