Ad-Hoc Activity Reassignment in Workflow

Hi,

I understand that we can do the following

Login to Workflow Management Console as a user with Administrator role, and manually re-assign the approval activity to someone else.

1. Navigate to Monitor Apps > Running Processes
2. Click into the targeted process instance
3. Click into the targeted activity for details
4. Click at the "Reassign User" button, and choose an assignee

However, I'm looking at the possibility to do this reassignment using a Form built on Form Builder because we do not want users to go to the Workflow Management Console with Administrator Role. I believe task reassignment is a norm in business processes because of unforeseen constraints.

Anyone has suggestions? Appreciate it much. Thanks.
