If I understand this correctly, we're rather talking about some sort of 
abbrivation - or rather an alias. If I'm not mistaking, there is a
WITH / END WITH for object manipulation in VB (Not sure if it where there 
I saw it) which lets you modify an object without having to give reference 
to the whole 'path', ie. instead of writing the line 
'myObject.myfield.lines.text', you could write 
WITH myObject.myfield.lines DO
  .text = 'This is a test'
  .colour = Blue
  .. etc.
END WITH

Sorry if I totally misunderstood this... :D
