According to the WebAssist tutorial for Server Behaviors for the Creative Cloud you are able to enable the deprecated server behaviors panel.
However, it appears that DW CC (2014) has done away with this ability as it does not have a DisabledFeatures folder nor a Deprecated_ServerBehaviorsPanel_Support.zxp file anywhere within any of the CC downloadable files.
I'm assuming WA is already aware of this on the heels of releasing an extension requiring this functionality.
