DS90UB953A-Q1: A single serializer for two sensor cameras

Hi,
We are using the 953/954/960 in our product design.  They work wonderful.
I have been searching for a serializer to handle two camera sensors with a single IC (two CSI lines for each camera or even 4 cameras with one single CSI line per camera).
in simple words: no extra ICs to aggregate the multi stream at the serializer.
There are a few old similar questions about this topic, but no more information or updates about it since then.

My specific question: Do you have a plan in the near future to release a serializer capable to split the single CSI2 4 lines in double CSI-2 sensors  with 2 lines each?  (or something similar in the near future)

We have an extremely limited space and one single serializer IC for multiple sensors will be a perfect fit for our application.

Thanks.
