Adding external PCIe expansion chassis to HP Z4 workstation

[Hyezion]

To test a product, I'm looking to use Z4 G4 work station to interface to PCIe test instruments to execute tests. The Z4 comes with 5 PCIe slots, but I will require more slots. One option is to use an external PCIe expansion chassis, which requires a bridge hardware to connect the Z4 to the external PCIe expansion chassis. Can the Z4 accommodate 13 PCIe slots (5 slots on Z4 and 8 slots on expansion chassis)? If it can accommodate more PCIe slots, where can I find instructions to configure the BIOS to add more PCIe slots and also assign slot numbers?
