Frame IO overwrites a previous export if the sequence is duplicated and renamed

Frustratingly I export a timeline to FrameIO for review. I send this review link to the client. I have another version to do so I dupliate the sequence and rename it. Once I made the various changes I also export this sequence to Frame IO for review. BUT Frame IO will overwrite the previous seqeunce. 

Now my client has a review link for the wrong video! Please fix
