How to Show Macintosh HD - Data on Desktop?

HI Apple,

I recently updated to macOS Catalina. I understand that there is a Read Only Disk with the name "Macintosh HD" which has all the files related to OS and "Macintosh HD - Data" which is Read/Write. But when I use option "Finder->Preferences->General->Show these items on desktop: Hard Disks" I get "Macintosh HD" not "Macintosh HD - Data". Right now If I have to open "Macintosh HD - Data" I have set it as default in "Finder->Preferences->General->New Finder Window Shows:->Selected Volume of Macintosh HD - Data". But every-time when I want to open "Macintosh HD - Data" I need to go to "Finder->New Finder Window". Is there an option to make "Macintosh HD - Data" as default so that I always open "Macintosh HD - Data" when I Click on Machintosh - HD Icon on Desktop?

Thanks and Regards,
