I have a need to set up advanced ticket configuration within Odoo Online.  Are any of the following features available?

1. The ability to group individual tickets into a package - for example, if I have individual tickets at $10 each, but would like to have the ability to sell a table of 8 individuals for $70 (discounted) and track the 8 back to the maximum number of individuals so I don't oversell the event.
2. Is there a way to automatically assign a group? For example, if I buy a complete table of 8, then they would all be assigned to a specific table (say "Table #35").   If I buy individuals, then they get automatically assigned to a table that hasn't been allocated.
