QGC customization for automation tasks

Hello All,

I am making a submarine for a race with my team but we have some problems about it. Our weichle needs to do some automation missions in the pull but QGC is not compable with it or we couldn’t do it. So we decide to custamize QGC for automation missions but i don’t know where to start. I read the manual but still i need a some guidance.

If someone could throw some light on to this, that would be great.
