Thank you, a real improvement on this would be to be able to see a list of all my duplicate leads easily rather than having to review each lead individually.

In a similar way to an email rule, so if a new deal is generated from my form and one of the fields contains a certain word such as 'Virtual Reality' or 'VR' then add the tag that I've created called 'VR'.

Here's an example of how it works in Zoho Mail when a new email arrives.
