I don't know if anyone is interested but Hammer Core added this feature in recent update from 1.10 to 1.12
As of 9/9 2017, the 1.11.2 version of HammerCore does not appear to have gotten this feature. There is little sign on GitHub that the 1.11.2 version will be updated for anything.
Quote me to make sure I know you replied.
Useful stuff to help with commands in MC:
MCStacker <- The best /summon command generator out there. Also very useful for data tags on /give commands and /setblock and quite a few others.
minecraftjson <- Epic book/sign/title/tellraw creator. Turns hours of command creation into minutes!
Single command block <- Ever seen those epic single command block creations? This is how you make them!
http://chunkbase.com/apps/spawn-chunks-reader <- Shows you the spawn chunks of your MC seed.
