ILI9341 with STM32F0

Hello.
I'm playing with the STM32F072Discovery and it's great but I have a little problem.
I don't know how I can transfer data to the display via the SPI more efficiently.
For now I've configured it to work with DMA but it's no use because this display uses GPIO pin for D/C (data/command) and even with DMA I have to make a while loop to wait for a complete SPI transfer and an empty buffer because the display won't read correctly that pin.
Does someone have any idea how to do that?
This library http://dorkbotpdx.org/blog/paul/display_spi_optimization uses a feature of other microcontroller that has multiple hardware CS pins to control that but the STM32F0 has only one so that idea has no use here.
Thanks in advance for any advice.
