Not sure if this is possible, I was running the 12-13-14-a version of spigot (until today when i updated) and we discoverd last night that NON-OP players could access and change Command_Block information! Kinda crazy. I just updated to 01-13-15-a and this is resolved. SOooooo FYI for server owners who want to allow non-op's to mess with command_blocks Since it was fixed, i was wondering if there would be away to add this as an option the spigot config files? or perhaps to allow giveing a permissoin thur pex or something else to allow NON-OPS to access command_blocks. Thanks for considering.. and thanks for fixing this bug/glitch in thew newer snapshots. That was about to get bad on my server cause i use command blocks for LOTS of stuff.
