SPI with circular DMA and CRC not possible?

I need to receive a lot of SPI data on a STM32F4. To handle this, I use a DMA buffer in circular mode. Also, I need to use the CRC feature.
How ever this seems not to be possible with the HAL according to this note in stm32f4xx_hal_spi.c:
The CRC feature is not managed when the DMA circular mode is enabled

Is this only a restriction of the HAL?
Can I use the CRC feature with circular DMA if I implement the receiver myself?
How would I do this?
