If I call a method with an object passed by reference, how can I enable intellisense in the method?

local loObject as someclass of someclasslibrary
loObject=newobject('someclass','someclasslibrary')
** intellisense works here
** now call another method, passing object by reference
this.somemethod(@loObject)



**method somemethod
lparameters loPassedObject

** how do I get intellisense here for loPassedObject?
