SAS Studio Visual Programmer - Pass values to next task in process flow

[csteiz]

I've started learning how to write Custom Tasks.  I Wrote a Task to create a library in the process flow. I'd like to pass the name of the library to the next connected Custom Task in my process flow.  I am on SAS Studio v3.71 so I cannot yet use the DefaultValue option in DataSources. 

The documentation on writing Custom Tasks does not clearly explain if Tasks in a process flow can be configured to pass tasks to downstream tasks
