Wildcards in ALB listener rules

I'm trying to add rules to my listener in an ALB. The host headers are of the form:

example-1.com
example-2.com
example-3.com

Can we use a wildcard for this kind of host header, like this:

example-*.com

Are wildcard characters (*, ?) allowed in the middle of the url or path?

From this blog post from 2017, it appears that you can.

You can create Application Load Balancer rule that routes incoming traffic based on the domain name specified in the Host header

Rules that match the Host header can include up to three “*” (match 0 or more characters) or “?” (match 1 character) wildcards.
