I have been creating Service Catalog Templates and begun testing them. What I have found is that when I go back to edit the template and make changes to the Resource Info fields, this will retroactively change all the requests that used that template before - causing data to be lost on past requests.

Obviously this is not ideal for the sake of keeping our history accurate for auditing purposes. It seems the only way around it is to create new templates when we want to make revisions and keep the old ones hidden, which is something we are not keen on maintaining for all of our catalog templates. 

Is there a way we can edit Service Catalog Templates without it affecting requests that have already been submitted and completed?
