Hi Andrew!
You can use the Editable text Webpart for example and use a macro expression in the format: {% CurrentUser.CustomColumnName |(identity)GlobalAdministrator%}
This is an example "How to" :
First I created the custom column. Then I entered a value for a user. Third step was to insert th editable text webpart to the page and then I inserted the macro expression along with a separator "||"
The result is:

I hope this helps and wish you the best luck with Kentico.
