Origin or campaign and audit trail of custom forms

When we audit all the campaigns couple of years later, its very difficult to two things:
1. If someone has added or removed any custom forms. We have no audit trail on the campaign.

2. On the copied campaign, we never come to know how the campaign was created. Either it was created by a user through converting into a template, or it was copied from an old campaign.

Does anyone track that at your organisation?
