Amazon Connect now allows you to search for tags within an instance

Amazon Connect now provides the ability to search for existing tags within an instance, both programmatically via API and within the UI. When tagging resources, you can now search from pre-existing key:value pairs before creating new ones. For example, administrators can create a tag such as “Division:ConsumerCredit”, and users with permissions to tag resources within the same instance will be able to view and apply “Division:ConsumerCredit”, to save time and avoid mistakenly creating new variations of the intended tag such as “Division:CC” or “Div:ConsumerCredit”. To learn more about how to search for tags within an instance, see the Administrative Guide.
