That should work, but you have to disable the automatic retract by poweing it off. In addition, not sure what the shade would attach to, I do not remember is the awning has a slot for an attachment. On edit, after reading the instructions, I do not think so. The tension straps pull on the pole and awning together, not good. If the pole was able to be used without putting tension on awning, perhaps.
