Pretty sure these functions aren't part of the existing Rental module; if not where do I make a request for them to be considered?

1. Maximum rental term - we don't want our rentals to be longer than 7 days

2. Non-calculated pricing - If I want 6 days to be $15 then I want to be able to tell Odoo to ignore multipliers (such as 3 days is $3 x 2 = $6)
