News variables for Template Notification "Estimate" with Multi-Line Estimates

With the adaptation of Multi-Line Estimates, the notification mail "Estimate" use the infos of last job. The link included show all job lines, it'ok. But is it possible to obtain new variables for the "Estimate" email notification? The notification will make more sense if these new variables are added, otherwise it looks a bit odd (see attach).

1. Have a variable to display the order number only without the job number (Example: 12424)

2. Have a variable to display the list of jobs (numbers and names) in the order as a list.
