Feature Request

From a (long) list of selected proposals, orders and invoices I would like to have 2 mass actions.

• Add object's Thirdparty to a Mass Mailing Target
• Add (external) Contacts of object to a Mass Mailing Target

In both cases I would like to only add new email addresses which are not already the in the list of targets of a new or the selected Mass Mailing.

Use case

I organize dance events using Dolibarr, and I would love for it to be easily possible to make mass mailings for possible these targets which I can easily find using the list of proposals, orders and invoices where I can search on Project and Complementary attributes, which means I can easily make lists for:

• volunteers
• Fully Paid participants
• Accepted but unpaid
• Waiting list of not yet accepted
• VIP's
• after event people who did a checkin (order marked delivered) for surveys

• possibly if I have to change the location of one class, I'd love to quickly make a new list for just the participants in this class telling them the new location. (YES, there might be more than 25 people in one class). But imagine it was a concert where we had to change the venue and had to tell hundreds of people?
