I thought of that but the Hood 9XX unit I had wouldn't allow that as there was a fixed cover over the rotating grip drum part so there was nothing to lash to and thus no way to prevent the drum from rotating when the line slipped.
Other models may allow that which would be better than nothing, but still less suitable than a single line unit as you point out.
