How can I ignore response properties?

I’m trying ti avoid having a class to use internally and another class as the route response, and looking at the source code I found the ServiceStack.DataAnnotations.Ignore, but it does not seem to work as I assumed it would work:

is there a way to use the TransactionDate and CultureName but avoid this to be passed into the route response?

[Ignore] is only for ignoring columns in OrmLite, [IgnoreDataMember] is for DTO’s.
