getProp and passing values

Hi all. 

I seem to recall the ability to define a virtual custom property in such a way that I could for example code: 

put the maingriddata ["customers"] of card "Main" into tCustomersA

As is I cannot pass args to a getprop handler. I can only pass args to a setProp handler. 

Any ideas? I checked the dictionary and lessons. Not a peep.
