Replication + AlwaysOn MultiSubnet Availability Group

Just a quick rundown of my environment, Two SQL 2012 Instances with multiple databases in an AlwaysOn Multisubnet AG. With a third SQL 2012 instance is used for the distributor.

Following the documentation for enabling a replication publication on an AlwaysOn protected database advises me to issue the following stored procedure to redirect the original publisher to the AG listener name. Which causes issues for me. I believe the issues that I am seeing is because my AG is a MultiSubnet AG.

Any ideas how I might be able to force  clients when connecting the redirected publisher to include the MultiSubnetFailover=true connection string parameter would be helpful.

Thanks
