Screened/Covered Porch - Door/Stairs

[05uurx]

I'm drawing a screened porch, no screens yet, i add those later...i want a 36" screen door in the center and a simple stair going from deck height to ground level. After i place my door, i draw my stairs - using ALT to reverse the direction so they go down instead of up.

Now, here is my question, when i adjust the width of the stairs in front of the screen door, it also adjusts the door width, see the 2 attached images for illustration. Is there a way to adjust the stair width independently to the door?
