This is a very easy mod to do with the Scarp 1/2 and several other shelters like the Rainbow/DR and Moment and Notch .
Just attach some shock cord to the corners and clip that onto the mitten hooks at the bottom of the Pitch Lock corner.

Just for the exercise I attached the shock cord using a piece of tape , you could add some tape there and punch in a grommet if you wanted a neater finish.
My mock up floor was for a 2 person tent so it is about 1/3rd larger than it should be (the Tyvek is folded in on one side) but still fits inside the stuff sack if you fold and roll carefully.
Note that I do it by gathering all of the struts at one end and then roll it in using the cross pole from the other end (the middle of the tent fly)
