Update Saved Message Template Blocks Cascade Changes To Existing Emails With Said Blocks

If you save message template blocks in either user templates and/or bulk messages, and you need to change a saved block, the changes do not automatically cascade down the templates that use that block. You have to manually open each item and drag and drop the new block into place and delete the old one. This can get extensive when you have 100s of templated messages in use. There should be a save and save as option, where save overwrites the existing block and cascades the changes to any template that currently uses it.
