Can you assign a diferenet ringtones to a contact with two numbers?

[JunWalker14]

Just purchase my Motorola Droid Razr and all my numbers were ported over to it.
My Wife has two numbers in her profile - the home number and her cell number.
I would like to assign a ringtone for her cell number and a different one for the home number which is in her profile.

I do have others with two numbers and would like to do the same. (with all the ringtones out there it would be fun)

Thanks

Cheers
