The ability to switch between all the Creo applications "on the fly"

Now launch Creo parametric, creo direct, creo schematics, creo Illustrate, creo view only via separate shortcuts. Unable to launch other application from existing launching application,

I think PTC should provide the ability to switch between all the applications "on the fly", for example, switch from Creo Parametric to Creo Direct ,Creo View MCAD or Creo Illustrate, just like CATIA style. Or can launch other applications from one existing application.
