3 Wishlist: Calculation total rental price depending on number of rented vehicles

At the moment OS CCK calculates the price only for one vehicle depending on the duration of rental days.
But I saw, it is also possible to select an amount to the price field how many vehicles (items) one want to rent (buy). I know, this feature is only for the "buying function" of the shopping card.
But it would be wonderful, if the CCK rental function takes this in concideration and would be able to calculate the total price beside the length of the rental period also on the amount of vehicles (items) the customer likes to rent.

If you rent a car, it is usually only one car. But if you rent motorbikes or bicycles or accesories it could be more than one. For instance, if the whole family likes to book 5 bicycles for all family members.
At the moment, if you have 10 bicycles of the same type (A) to rent and 20 bicycles of another type ( you have to create 10 instance for each bike of type A with the same photos and bike features and 20 instances of type B. In the frontend listing the customer will see 10 bikesof type A and 20 bikes of type B which will him confuse very much.

I know that one has to modify the table structure and the availability in the calendar if one can select also the amount of rent vehicles. But with this additional rental feature CCK would be more flexible.

Mabye another solution could be to put a button "continue rental" as in the shopping card layout. So the customers can choose another item (car/motorbike/bike) to rent in the same booking process. But the customer still will see plenty of bikes/cars/motorbikes of the same type in the frontend. The frontend will get overburden.

At the moment, if you have 10 bicycles of the same type (A) to rent and 20 bicycles of another type
There all go from as example CAR, every car have some unique identificator (VIN code) so by this VIN code - you may check for history of this car. So if you will move to rent 20 cars - you will need fill data for every so car,


But YES with Price fields in our Website builder - there very many thing need add

May bye another solution could be to put a button "continue rental"
This you may add to any our layout as custom field, and add there link where to you need
