Second iCloud Account for Reminders

Hello. My iPhone allows me to see the reminders I have in two different cloud account but I can't figure out how to do the same on my mac. I will call the cloud accounts Primary and Secondary. I'm signed into the Primary cloud account on my phone and my mac with Reminders selected. On the iPhone I can see my reminders for both Primary and Secondary and can select the Secondary as my default for new reminders.

On the Mac I can only see Primary reminders and thus can't select the Secondary account as the default for new reminders.

Is this a feature I can only get in IOS?

Thanks in advance!
