I don't believe there is the ability to select more than one value in any of the ticket field options available in Freshdesk , this has caused us to have to create multiple fields to capture similar data. Since there is no way to do this there should be a way to add the selection of values across the fields.
For example:
We are trying to capture the errors that are reported on our tickets by our clients.
We had to create 3 error fields because Freshdesk does not have the option to select multiple values in the drop down ticket field.
It would be nice if there was a radio button option or an option on the drop down ticket field where you can select more than one value. (<-this would solve all of the issues in this feature request)
Currently, to track the three fields they have to be counted separately . We need a way to sum them all together. You can sum the count of multiple fields together in SQL so this should be something that your developers can make happen
