Add an option to avoid agents creating duplicate tickets for same incident

From the JSM perspective, it would be really great to have the option to avoid duplicate ticket creation by the agents/users for the same issue. This will certainly add value to the product as it will help in achieving quality in issue reporting.

Options that I can think of are(not limited to),

• Displaying a list of OPEN issues reported by the same user with the summary- this could help in preventing creation of duplicate tickets from same user
• While typing SUMMARY, match the keywords/errors and suggest if it is similar to an ongoing issue
• An option to add impacted customers to the same ticket rather than creating multiple tickets for the same incident
