Configuring LTO4 and LTO5 media on Netbackup 7.1

We just upgraded to a new Quantum library with drives that work with both LTO4 and LTO5 media, but Netbackup 7.1 only discerns the media as HCART, not HCART4 and HCART5. Is there an update to Netbackup since the following article was written that introduces the HCART4 and HCART5 media types?

I need to differentiate between the media types in the policies so that I can control the media usage.

Any help is appreciated!
