We ran into the same problem
We’re new to Monday, and are still figuring out what’s the best way for us to use the platform and it’s many great automations.
We set up boards, ended up deleting them and recreating them using a template that better suited our needs after the first couple of weeks of use, but now making new changes to that template requires us to recreate all of the boards in it’s image again (including the tedious step of migrating all the Pulses), or having to apply the change on each board separately.
This is relevant by the way not only to automations, but also to other column structures etc…
I would personally love for a template to be like a master slide - updating boards built in it’s image.
