[SDF-60606,SDF-66538] additional variables for reply templates

could you create variables like
1. list of Cc recipients,
2. when was email sent
3. last reply,
4. all previous conversations (like when you hit reply button)  - I am asking for this because when you create reply template I do not know how to add there previous conversations with variables just description.
