AF remap on F1 vs. F3 series

In previous design, where we used STM32F103 we could have two alternate functions on the same pin. It was SPI CLK (used for SSI protocol) and TIM2_CH2 which was configured that every CLK edge reset CNT register (used for SSI timeout). That was possible because you can specify in AFIO_MAPR registers where should each peripheral be mapped.

It seems that in STM32F303 this is not possible. There you have only one field for each pin in GPIO_AFRH / GPIO_AFRL registers where you can specify which function will be connected to it.

So, is it true that here we cannot have SPI CLK and timer input configured on the same pin? Am I right? Thanks
