Question about mission setting via pymavlink with QGC

Hi, all.

I am trying to test PX4 SITL connected with QGC.
Currently, I want to set a number of missions via pymavlink while missions appear in QGC.
Although I succeeded in sending missions, such missions do not appear in QGC interface and mavros (I checked mavros with “rosrun mavros mavwp show” command).
Furthermore, its missions seem to disappear after I re-run the SITL.
Although it does not matter to me, it may indicate there is something wrong when I upload missions.

I am wondering whether it is possible to make my sent missions via pymavlink appear in QGC.

Thank you
