Set world coordinate system origin to a new location?

Question

In Minecraft creative mode, is there any way to set the 0,0,0 origin point of the coordinate system to a specific location?

It would make the mental arithmetic much more convenient when I am building stuff with lots of /fill and /copyblocks. Right now, I am writing down the coordinates of reference points, and offsetting everything by their coordinates, every time. What I would like, would be to be able to refer to the north-west corner of a structure that I am building as 0,0,0, and the far corner as $width,$height,$length.

I'm on PC, v1.10.2.

While there's no way to do exactly that, you could place an armor stand with a tag or name on the new origin:

/summon armor_stand X Y Z {Tags:["origin"]}

Then you can use the following command to use this as origin:

/execute @e[tag=origin] ~ ~ ~ <your command>
