Cross Bleed start impossible

[Graziani]

Hello Umberto

I try to starting the engines by Cross Bleed procedure but GSX ask me to start APU (ON).
Why for some procedures I need to follow GSX ? If I want engines start without APU.... I think that for this things the Pilot in Command should decide.
Because while I start the APU .. I can not follow with the pushback

Can you enlighten me?
