If you want to do an auto bleed that's the way it's done.

A Tech2 clone is $259. I own one. They work.
GM VXDiag is around $110 and it comes with Tech2Win and TIS2000. You need a Windows laptop to go this route and those aren't free. The NAO 33.004 Tech2 BIN file is available on the Tech2 Wiki if it's not shipped with the VXDiag tool.

The Snap On Solus tools can be had used for just under a grand.
AutoEnginuity can do it as well but you need a laptop and the cost is right around $500.
There are probably a handful of other tools in the $500 on up range that can do it on some but not all ABS systems.

The nice thing about the T800 master cylinder is the round three tab cap that takes one of the leak free pressure bleeder adapters...
