Possibility of "alias" references within a graph in order to document once but reuse it multiple times

Question

Hi all,

I'm still quite new to this exciting tool and maybe I'm not using it the way it should be used...but here is my thing I'd like to be getting solved:

1. I'm "reverse engineering" a piece of software, which is written in a structured programming language.
2. For this I'm using mainly BPMN elements.
3. Within the module there are several functions, subroutine calls, procedures, etc.
4. One procedure is called several times on various locations
5. I've documented what is going on inside this procedure within a group node.
6. Now I'd like to "link" all occurrences of this procedure calls to the one documented group node, so that if there is a change it only has to be changed once.

 

Sketched code for a better understanding. DOC_PROC is my documented group node, and I'd like to create an alias within Internal_A and Internal_B.

START HUGO:

CALL INTERNAL_A

CALL INTERNAL_B

START INTERNAL_A:

CALL DOK_PROC

END INTERNAL_A:

START INTERNAL_B:

CALL DOK_PROC

END INTERNAL_B:

END HUGO

 

Thanks and best regards,
