Is it possible to assign number of cPanel accounts to a reseller package

[Mechanic]

Hi,

Is it possible to create a reseller hosting package and give the client a choice of how many cPanel accounts they want in a radio button/text field/drop down?

For example, when a client orders the reseller1 reseller hosting package, he will be given 3 options: 10 cPanel accounts, 20 cPanel accounts or 30 cPanel accounts. If the client chooses an option and an additional amount will be added to his invoice.

Is this possible?
