I need directing helppp

So basically I am pretty dumb and don’t know how to do this. But anyway, how do I open a scene with characters already in the scene rather than having them enter manually? Thanks x

@CHAR stands position

thank you, but how can i make her face right aswell?
this is the scripting i have so far:

EXT. MANHATTAN SKYLINE CAR LOOP - NIGHT

@JANELLAH stands screen left

@JANELLAH stands screen left AND JANELLAH faces right/left

thank you
