Screen for Workflow starting transaction

[Ramkumar, Govindasamy]

Hi Workflowers,
 
While creating starting transaction for a workflow using transaction SWUG,
the default screen generates fields for "Adhoc Objects and Attached Objects
in the table format".
 
Is it possible to hide these fields?  If so,  how to do it?
 
Should the starting transaction screen be generated using SWUG or can I
create a simple screen using screen painter and attach it to the Workflow
transaction? What is the transaction to attach the screen created using
Screen Painter?
 
Thanks in advance for your help.
 
Best Regards
Ram
