Campaign Default settings - New messages default to choice of approved or unapproved
In the campaigns, allow for setting that let you change your default settings for each campaign, or all campaigns. Including default all new posts to approved or unapproved when created. Currently it defaults to approved, then i have to manually change it to unapproved for review.
Changing the account privileges to contributor handicaps the specific account, and is a nuke option for something that could be fixed at the campaign level if there were an option to change your default campaign settings.
Your best bet to force approvals on a per-User basis is to set up a Custom User Role. With this feature, you can allow Users any set of permissions, while preventing them from being able to approve their own posts.
If it’s more of a convenience thing where you would rather it toggle the default one way or another, our new Workflows update sets your last “post” option as toggled, so if you want to make several approval posts, after setting the first one to “Send to Approval” the next posts you create will also show “Send to Approval” as the default action rather than “Share now/Schedule”.
