SubProperty for properties in PP8.5

Hello All,

   Is it possible to create nested properties in PP 8.5, by which I mean

Prop1=>subProp1

         => subProp2 =>Subprop3...

.

.

.

The reason I want this is so when I convert to JSON, I get

prop1.subprop1

prop1.subprop2.subprop3

etc...

I could do this all in Java and have it excute via java on client component.. But wanted to know if I could do using built in components...

Thanks in Advance...
