The original Teensy 3's implemented a background continuous touch sensing mode in hardware, but the Teensy LC and Teensy 3.6 don't. I suspect that it can be done with a DMA program: transfer pad number to touch sense register, start measurement, wait for measurement to complete, transfer measurement result to memory, step to next pad, start over from first pad when list is exhausted. Are any good examples of this sort of Teensy DMA programming around?
