In workshops it is possible to mark all workshops that are not in production.
And then mark what needs to be produced.
Want the same function for factories.
A player on the US forum @ashrem gave a good explanation why this won't work. Basically, if you do not have enough coins or supplies or seeds, etc to start all the productions, the game will not know which ones to actually start.
Exactly. Change the button to like other times when you don't have enough stuff to start production.

exactly
just need a simple query before this command executes and if it finds that there are not enough resources it should generate an error message and abort the operation
easy-peasy
