DRV8873: iProp Question

Part Number:DRV8873

Regarding DRV8873, my understanding from the data sheet is that you can connect the 2 iProp lines together and their currents will add.  I have 3 DRV8873 where I use 6 half bridges and only run one at a time.  Can I connect all 6 iProp lines to one resistor?  I only need to sense one current because I only turn on one of the 6 half bridges at a time.

Thanks!
