More than one sampling at the same time

Dear experts,
Isn't it possible to execute more than one hotspot sampling at the same time with VTune Amplifier XE?
I am trying to perform both collections at the same time:
amplxe-cl.exe -collect lightweight-hotspots -result-dir=BasketballDrive TAppEncoder.exe
amplxe-cl.exe -collect lightweight-hotspots -result-dir=BQTerrace HMEncoder.exe
but the following error shows up when I try to set up the second one:
ERROR - A sampling session is already in progress - Abort current run.
Error: Sampling session is already in progress.
Error in sampling collector. Error code - 57
Best regards,
G. Correa.

PMU resource can only be accessed by one process of the product, at a time.

Use hotspots instead of lightweight-hotspots, can run two sessions at same time.
