How do I push an update to an item in all my sub-accounts?

Every item in the Library has a version number. Each time you update the item in your agency (master) account, the version number changes.

1. Go to the Library and open the item.
2. Choose Apply to subaccount.
3. Select the sub-accounts. You can select all of them.
4. Apply.

You do not need to make the change in 10 or 100 accounts by hand.
