Audit Table by Access - and the effect with many external tables

Hello:

My company asks that the DBAs audit DDL statements in production, so we use "audit table by access"

This was fine until we installed an application that relies on reading thousands of XML files daily - as external tables.  Won't each read trigger a "create table" audit entry in sys.aud$?  If so, is there a way, without having to implement FGA, to not record just these actions?

Thank you,
