Attach more than one link to sap workflow task

Hi ,

Actually I am developed one workflow for specific requirement but I am facing one issue .

• I have already attached one link for one transaction let's say ( MM03 ) using class default method .
• Also I have used program exit for creating another link ( url link ) .

But the issue is I have to add another link for another transaction (MM01) to sap workflow task because using class default method only one link ( transaction ) can be generated and using program exit document attachment can be done.

Pls guide me how to add another transaction link ( means t code link ).

Thank you.
