How to give initial guess to /diff_drive_controller/odom

[PeppePercival]

ISSUE TEMPLATE ver. 0.4.0
Thank you for contributing to Science, you're great!
I want to plot the topics of /diff_drive_controller/odom and /ground_truth via plotjuggler. I changed the x_pose from gazebo.launch.py to -2.0 to match with the environment but i can see the diff drive controller x position is at 0.0 but the ground truth is at -2.0. How can i set -2.0 for diff drive controller too as initial starting positiono to then follo ground truth and my extended kalman filter?
