Pricing configurable options value depending on another value

I have a record in the configurable options called

Accounts

which is a select menu contains

[10,50,100,200]

and another record called

Points

and I want to set a price for the

Points

to be like

 Points Price + ( Accounts Count * 0.25) 

But I only can set a fixed price not dynamic one. Is what am I seeking is doable??

not currently - though it is hoped by many users that when WHMCS release their new order forms, that it may be.
