We serve 3 regions and therefore have 3 different 'book in a call' links based on timezones. I want to be able to create one dynamic content block for 'booking in calls' and insert it into all of my emails (rather than having to replicate the same dynamic content block into every email we send).
Then anyone creating emails can use this dynamic content block, and also if the links or regions change, I only need to update it in one place.
