Predefinded rental days (variants)

Hi there,

is it possible to predefine days as “variants”?
E.g. 3 ($20), 7 ($22,5), 14 ($28), 30 ($47) days

And then also add more than one extra day?
Also booking should only be available one week after now.

Would be perfect, searching for such a plugin a while…

Regards
Philipp
