oops, we forgot that,

I’m not 100% sure but I guess this would be a looooot of work as it requires opening the doc, loading the first page, taking a snapshot and save it… I don’t think we’ll do this anytime soon – also it’s just the second time we hear it.
Just FYI, on top of the list we have the "shared tabbles" feature (check here).

Cheers,
