Thanks. If it is from the library, then it is not custom. 😉 A custom stair is created via the "Create Stair" button at the top right of the Stair Settings dialog. Assume you are using "Stair L-Shape 15"...
Anyway, just mirror it. Click the mirror button as shown in the attached. Or, select the placed stair and issue the mirror command (either pet palette, Edit menu, or shortcut - ctrl-M) and give the mirroring axis.
