SQL Server 2014 AG + Clustered Shared Volume

I am testing this scenario in a lab environment:

Node 1 + Node 2 = Failover Instance

Node 3 = Secondary Availability Group.

I am using Shared Clustered Volumes for the Failover Cluster. This causes the volumes to appear on NODE 3 with the same paths. 

That is expected.

Problem: If I add a datafile on the failover instance, it tries to add the file to Node 3 using the original path. This fails. 

Because, that path already exists and locked as it's Node1/2's cluster volume path.

Any workarounds? With CSV, do I have to have different database locations? Is there any way to modify the clustered volume on one node only or drop from a node in the cluster without dropping the node from the cluster.

Thanks
