What I would do is build up a custom string attribute on sending out the email.
Probably you have a specific entity for the token replacement? You can add the attribute there.
Then when sending the email you can retrievethe UserTaskViewList through the Workflowview(depending on your set up the path can be a bit different)
The in loop build up a string variable to show something like:
- Date, Approver, Status
- Date – Approver, Status
You could add html to the string to show it in a specific design.
Hope this helps
