Yes you can.  Not only can you edit existing elements of the TimeControl Menu, but you can add to it also.  In the Administration Tab there is a selection called Menu entry.  Using this function, you can move menu items from tab to tab or add a new entry.  Imagine that you’ve created an internal project management tracking process manual and you’d like to make sure that all of your TimeControl users can access it from right inside TimeControl.  You can click Add in the Menu Entry module and add the URL and an icon for that selection.  Once you’ve added the new entry, it will immediately become visible in the User Profiles module in case you want to make sure it is secured for one user or another.

Or, imagine that you’ve created different manuals for different users perhaps for users in a particular country.  You could create manuals for each country and a menu item for each and then use User Profiles to only show the appropriate manual to someone in that country. 

The same goes for any other function you’d like to create.  The URL destination of a menu item could also be an external system.  This type of flexibility is powerful so you need to keep track of what you’ve added to your TimeControl so you can train people on finding the right function in the right place.
