Expression to access information of/from a process or process model

Is there a way to use an expression to access information of/from a process or process model?

Basically I'm trying to create an expression where you input a process model number and it returns a certain process variable for all active processes in the model.

I know this could be done by creating a process backed record and then querying the record. But can this be done without creating records just in the expression editor?
