Reusable blocks with reference in Email Designer

Hi,

it would be great to have reusable blocks that can be referenced in Marketing Emails. 

Scenario: The Footer for Marketing Emails changes (new grafics, differnete wording ect). There are several Trigger Emails that are actively used in running campaigns. Since the footer changed with the current functionality every email has to be copied, the element from the footer has to be changed, the running campaign has to be stopped, and in case there are transitions in the campaign that depend on the old trigger email, the whole campaign has to be set up again.

Business value: For companies that are using a lot of campaigns with trigger emails the effort for maintenance would be reduced significantly. 

With reusable blocks that are referenceable the change of an element in Emails can be done in the block and the Emails that use the reference are updated automatically.

For reference: SAP Marketing Cloud already offers that feature.

In case you have any questions regarding this please let me know. I would love to see that feature in furture versions.
