Would be very useful when using Zapier / Integromat to be able to create a New List from a saved Template.
So you could essentially build more conditional workflows.
If you have a WooCommerce product setup and you're selling say, Business Card Designs - you could use each new order as a trigger in the workflow and then the action could be to create a New List from Template.
With Zapier + Integromat's growing array of filtering / routing options - this would open up a ton of opportunities for hyper optimized workflows.
