Does Appian support Nested Multiple CDTs

@nimishan, decide on what approach you find suitable. Approach given by @sikhivahans is also good.

A few points to note:
1. Set PV is synchronous - the smart service will not proceed unless the "Set/Get PV" updates the PV in the target process. So, you should use this if you do not want to proceed further execution unless the value in target process is updated.
2. IFM - I am not sure if it is synchronous or not.

Send/Receive message is asynchronous, use this if you don't want to wait for the PV to get updated in the target process. If you intend to use Send/Receive message, make sure that you target the process instance using the process id. Its performance friendly. And good thing is it can reduce any dependency on plugins. Its a good thing to rely on in-built methods as long as you can.
