We await some feedback from @PavelBal on how much simulation duration will be affected by setting this flag to true by default for all processes.

The flag cannot be set during export because at that time, the simulation is already constructed. The flag must be set in PK-Sim during initial construction of the simulation model.

Aren’t we constructed a new simulation? Or just the building blocks ?

i don’t think we should set this flag by default to true

@PavelBal check performance of the resulting simulation
