Will serialization factor of 6 in LVDS serdes IP be supported in the future on Agilex5?

I was hoping to use LVDS serdes IP to implement acquisition system of 12 -bit ADC data using 2-wire LVDS: 

However, this is not possible if only serialization factors of 4 and 8 are supported.

Is there a workaround or will this be supported in the future?
