Dynamic Maintenance Fields in Subjects of Emails

We have dynamic fields for email templates, such as [[tenant.firstname]].
We also have all of the maintenance fields here, so you can show the maintenance information on the email itself.
Now we also added support for these maintenance fields in the subject line of the emails.
You just need to click anywhere in the body of the email, click on Insert Datafield to add in a field, and then choose the maintenance field. Then cut and paste this entire field ( [[maintenance_request.subject]] ), including the brackets [[]], into the subject line of the email.
It will show just like the other dynamic fields do in the subject, and then once the email is being sent, it will fill in these fields with the data of the field.
