Hi Carina.
This is Louis van Amelsfort. Member of the CA Service Catalog Support Team.
In answer to your question, for the moment there is no option to do so.
In the past, several DAR/Enhancement Requests have been raised for this.
Currently, I want to ask you to addan 'Idea' in this community for this.
Once done, I'll vote for it then.
Thanks for your understanding on this and kind regards, Louis.
