I just tried manually setting the white balance with the pop-up flash - this worked fine, I'm fairly confident that this process will also work with studio flash - I will give this a try tomorrow in my studio and let you know.
Anyway - I think that flash colour temperature doesn't vary a lot - so you ought to be able to use the built-in "flash" white balance setting. Using the modelling lights will be a bit risky - Even IF the correct bulbs are fitted. My 2c.
