I had some concerns about this as well with our 365saq. I wanted to make sure I could get the 3 slideouts open on the drivers side and keep the other one closed so we could pull up on the street in front of the house and load. The street is wide anyway, and we're in the middle of a neighborhood, so we have very few cars that drive down, but I wanted to be courteous. I asked the dealer about installing something that would hold the side on that side back. He stated there's only one pump and they generally will slide out in the order of ease. He said the hydraulic pump will push the easiest one first which always seems to be our bedroom. Then one of two things happen. Either the super slide and the drivers side rear bunk will come out at the same time, or the superslide by itself and the rear bunks both side out together. This is a problem for me, because I don't want the one side open. Believe it or not, just a little pressure changes everything. If the slide I don't want to go out starts, I stop the switch, get my wife to hold it instead, and I go outside and lean against the slideout. Works everytime. I put just enough friction against it, that it pushes the other one and as long as my wife stops when I tell her to, we get the ones out we want and not the others. I hope this helps.
