Processes - access return values

Hi Experts,

Is there a way to access the return values of the Processes in another process in integration?

(As same as we use in the mapping tab? {functionname:return value})

Example 

Process 1 - function - creates a unique identifier

Process 2 - access the value return by the Process 1 

I know that we can use some workaround by saving this value to another user def field and accessing it. But the customer wants to check whether there is a direct way to do it.

This is not possible as per my understanding.

Highly appreciate your feedback on this.

Thanks,

Hasara
