Can we add stair via RIR?

Hi all, I wonder if we can add stair via RIR. I try to search but with no luck.
Is there other way around to add stair?

Many thanks,

That would be a fairly complex programmatic workflow, please see the thread below.

We also have a guide that demonstrates a workaround of creating a system family template that uses a stair as the example.

Thanks Japhy, will have a study on it
