It would make the Saved Items feature in the email editor a lot more functional if it was possible to delete or edit those. And even better if it were possible to globally control these, so that if they appear in automations, they can be updated in one place and need not be updated in each email where they appear (e.g. sometimes I have an automation-specific opt-out text block that I want to control globally across multiple emails).
Ideally, these would be:
a) accessible and manageable under the email marketing section (probably placed to the right of Templates tab—see the attached screenshot with red arrow)
b) able to be added as a globally synced block with the ability to "detach" or customize (similar to Elementor global widgets)
The essential, simplest implementation of this request would be to make it possible to delete old Saved Items. Right now, they just accrue. If a change is made and a new version is saved, it would at least be helpful if the old one can be deleted.
