I can't think of an easy way to make the plots have a different arrangement.
I'm guessing you are using rstool, is that right? If you use fitlm and the plotSlice function, then there is a Predictors menu to select the predictors to plot. You could run plotSlice multiple times to select different subsets of the predictors for the separate figures. The plots are disconnected, though, so changing a predictor in one plot would not affect the other plots.
load hald
lm = fitlm(ingredients,heat,'interactions')
plotSlice(lm)
Also, the plotEffects function is another way to compare main effects in a linear model.
