Its similar to thread you linked. Create file “_headerModuleList.tpl” in “/custom/themes/SuiteP/tpls/”. Paste contents of orginal file “_headerModuleList.tpl” located in “/themes/SuiteP/tpsl/” to newly created file. Now modyfi new file below line 505 where you can find ul list containing menu. After this do quick rebuild.
not without making changes to core files.
you would need to find the display class for the header
and then add conditionals to check the current signed in user against some criteria.
you could then provide different quick create options as an array into the template and then loop on this array to print out the HTML.
you could also assign variables from within a template however I strongly advise against this
