[Question] Scrolling two big lists synchronously?

[vinaybedre]

Hi,

I am trying to build a screen, where we have a horizontal calendar on top which scrolls horizontally and a vertical calendar on the bottom.

An example picked up from Supershift

When we scroll bottom vertical calendar, top horizontal calendar should also scroll in sync and vice versa.
Both the calendars are using big-list. Is there a way on how to achieve such a thing?

Any hints are appreciated.
