You can try the unofficial patchset (https://sourceforge.net/u/uecasm/etherlab-patches/ci/default/tree/#readme).

While it can't do it completely in parallel without consuming a lot of bandwidth and risking breaking the realtime cycle, one of the feature patches that this includes allows scanning and configuration to occur in parallel up to the configured bandwidth limits.  With default settings this results in blocks of 16 slaves at a time being configured in parallel.
