Add feature: "Description of ticket" is mandatory before ticket is solved/closed

[TTAdem]

Hi,

We use ticket templates with the ticket "description" as mandatory field (amongst others) and it works fine when creating tickets manually.
But when a ticket is created by E-mail it can happen that the user/technician does not put anything in the content of the E-mail but only in the subject as description of the requests/issues.

The behavior plugin allow to put several fields as mandatory before to solve/close ticket but not the " ticket description" field.

Is is possible to ensure that the "ticket description" field is also mandatory before to solve/close a ticket so that the technician have to add a more detailed description of the ticket?
Plugin version: 2.7.3
Thank you for your support,
Regards,
