Mailgun sending AND receiving using wildcard subdomains

I want to be able to send from foo@*.mydomain.com AND receive responses without needing to manually setup MX records for each subdomain I'm interested in (bar.mydomain.com, baz.mydomain.com, etc.mydomain.com , ...)

Mailgun docs show a setting on a domain called wildcard labeled "Mailgun allows you to receive email at multiple subdomains of a single domain without actually adding them. You still need to add the appropriate MX records for your subdomain(s) at your DNS provider" in the web ui.

A comment on this ServerFault answer seems to hint that a new MX record would have to be made for each subdomain. I'd prefer not to have to do that and just keep it dynamic with something like this:

@                IN  MX  10  mxa.mailgun.org.
@                IN  MX  10  mxb.mailgun.org.
*.mydomain.com.  IN  MX  10  mxa.mailgun.org.
*.mydomain.com.  IN  MX  10  mxb.mailgun.org.

Does Mailgun support sending AND receiving from wildcard subdomains? and if so, what DNS records should be added (MX & SPF/DKIM)?

(This somewhat related question doesn't list out the specifics.)

Just got a response from MG support

We do not support sending from wildcard domain. We require each domain you wish to send with be added and verified to our system with the explicitly SMTP credentials or API endpoint used for sending.
