Allow to use alias name to lookup the certificate from keysore at jdbc ssl transport layer

From the teiid 8.1 schema (jboss-teiid.xsd) under docs, there is no "alias" attribute defined for jdbc transport layer. Here is the question: in the case of there are multiple certificates defined at keysore, what certificate jdbc ssl will use? How to specify correct one to use?

Here is the sample teiid jdbc configuration used:

<transport name="jdbc" socket-binding="teiid-jdbc">
<authentication security-domain="mysecuritydomain"/>
<ssl mode="enabled" keymanagement-algorithm="SunX509">
<keystore name="/opt/test.keystore" password="password"/>
</ssl>
</transport>
