If you have 2 XMs, this is easy. Just run Detox Maintenance on one XM, and your preset on another.
With just 1 XM, use the BFBTool. Tick the Detox checkbox. Then in the Target Preset field, choose your already saved preset. Then click Build Preset, and the Remote preset will have simultaneous Detox and your programs. You need to be using Spooky Boost, and have the Remote on the High Power port.
