Dear Sir or Madam,
Is it possible to create "temporary stored Fields" (for example an Emergency Telephone Number to reach the customer).
Most of the time it is required to store Personal Information for a concrete business concern (which is possible in GDPR). But the option to "Forget" must be implemented. Therefore a deletion after ticket Close would be a nice Feature.
If there are fields especially for that purpose, it would be an ease to use and flexible solution.
