TIM2_TChx -> DMA_Channelx -> GPIOx_BSSR

I'm developing project on STM32L053.
I have 3 requirements regarding HW configuration and I'm not able to figure out one of them. I would like to ask here loudly whether this requirement is possible to fulfill on this silicon or not.

The thing is that I have to configure one of the compare channels (TIM2_CHx) on TIM2 to trigger DMA request to one of the DMA channels. This DMA request suppose to take next GPIOx_BSSR value and transfer it to GPIOx_BSSR.

Let's say I have 9 configurations for GPIOx_BSSR and every trigger should take next one - circular buffer which next record is selected with every trigger.

Is it possible to configure HW in such a way to fulfill this description?
