Select Faces and Edges command on Custom Panel

[gordow]

I frequently use the Select Faces and Edges command in the Quick Access Toolbar (QAT).  I would like to add the command to the Custom Panel on the Assemble Tab so I don't have to use the drop down menu, but when I am in Customize User Commands, I cannot find the command when on the Ribbon tab.  When on the Markup Menu tab, I can find it and add it to the Markup Menu, and I can add it as a keyboard shortcut.  I have searched the Ribbon tab but can't find the command there.  Why is it not available for the Custom Panel? 

Any insight welcome.  Thanks.

Hi

Do you know Shift + RMB combination?

Yes, thanks.  My question relates to how to put the command on the Custom Panel.
