Not able to relocate vehicle start position


I am new to QGC.

I am working with PX4 Simulator. By default, the vehicle position is located out of India. I am trying to plan a mission in India.

I am facing two difficulties:

  1. Not able to drag/move vehicle position
  2. To move waypoints to the desired location (which is far away), facing difficulty and taking time as waypoint editor does not have associated GPS locations. I edited GPS coordinates in the mission file. But could not change the vehicle start point.

Can anyone please help me?

Note: I did not connect the vehicle to QGC. I am currently working with the simulator(Jmavsim)

Thanks in advance!
