Multiple Non Metallic Pipe Through Slab 50Pa

Hi Matt, I was at your facility last week to the HFSC Level II Workshop. Great facility and fantastic presentations from all your staff. In particular, I really enjoyed "Johnny V's", Matt Winston's and your presentations. I was hoping that I could pick your brain with a firestop question. I know that there are probably no systems for multiple non metallic pipes through concrete slab with 50Pa but I might as well ask the expert anyways. I'm looking to see if Hilti has a system for two 1/2" PEX pipes penetrating a 2" cored hole through concrete slab requiring a two hour rating with 50Pa requirements. I have a hunch what the answer is but thought I'd ask anyways. Any feedback you can provide would be greatly appreciated.
