Enable to set a custom system property accessible from KNIME workflow

I’ve been dealing with some configuration challenges related to nested Wrapped Metanode recently which led me to an idea that it would be great if I had an option to set a system property from either command line (batch mode) or KNIME Analytics Platform.

I’ve investigated this a bit and I’ve learnt that it is impossible to set a custom system property using -vmargs -DmyPropertyName=myPropertyValue in the command the KNIME’s batch mode is started by. KNIME simply complains it doesn’t know the option you’re trying to set. Also, I haven’t found a way how to get custom system property available within a workflow while it is running in KNIME Analytics Platform.
