VR Straming Volumes: How can you take one object to an other map?

Hi everyone

I made a VR parcours for the oculus quest. The player can walk around a 6x6m room and explore different maps that load depending on the position of the player.
I have some grabbable objects for the player in some maps based on the default pickup cube.

Is it possible to transport grabbed objects with the player from one map to an other map?

putting them in the presisten level will not work for me,

thank you and

all the best
