Automating Timery/Toggl Timers with Shortcuts and Shortery

Inspired by on of MacSparky’s recent Labs posts, I have been trying to automate Timery with Shortcuts and the Shortery app for macOS since Shortcuts still does not have the ability to run shortcuts with automatic triggers. I’ve got things working well if I have just one timer running , but if I have the Music app being timed, and then want to read my Mail and also have that run a timer, the Music timer stops and the Mail timer starts. Is that just a limit that I will have to live with, or am I missing something? Can I start a second timer manually and then run both at once?
