UI action in Service Portal

[Vengeful]

I have a catalog item about recordings exception. It has variables Length of exception, Exception start date and Exception expiration date.

Once approved it will create a ctask.

Then if Exception expiration date is about to expire (15 days before the expiration date) it will send a notification to the requester. In the notification message, should be consist of if they want to extend their request.
Sample:

Request to extend exception? Click here: LINK

If the user click the link, they will be directed to their request to the Service Portal.
Then in the form there will be a variable Yes/No "Request Extension".
If Yes, it will show another variable 'Extension Request Date'. Then there should be a button Request Extension. Then it will go back to the approval process based on the workflow.
If No, a ctask will be created 'Recording Exception Removal'. 

Then end.

Not sure what your question is, but yes, it sounds possible.

It all depends on what you want to show the customer... you could pass them to a specific view via the URL in the notification which only contains specific fields; you could use a UI policy to show/hide and setReadOnly fields; you could use a task for the request extension piece.
