Engine.getMasterPeakLevel() on exported plugins

[ustk]

I know there's a flag for enabling the meters in exported plugins (ENABLE_ALL_PEAK_METERS)
It works for module.getCurrentLevel(), but not for Engine.getMasterPeakLevel()
I know I can place an additional module last in the chain and getCurrentLevel should do the trick...

I don't see any other flag for the master peak so is there something specific to do?
