Question To C M Ds

Just a question to the CMDs or people who are good with command blocks out there:

How do I summon an armor stand with a variation of an item (for example, a birch plank)? This is my current command:
/summon ArmorStand ~ ~ ~ {Invisible:1b,Equipment:[{id:"item goes here",Count:1b},{},{},{},{}]}
The problem is that when I try to put something with an ID like a variation, you have to format it like this:
<item ID> <# you want> <variable-thingy that changes variants>
Except it doesn't work if I do something like this:
/summon ArmorStand ~ ~ ~ {Invisible:1b,Equipment:[{id:"planks 1 2",Count:1b},{},{},{},{}]}
nor does it work with this:
/summon ArmorStand ~ ~ ~ {Invisible:1b,Equipment:[{id:"planks 2",Count:1b},{},{},{},{}]}

I ned halp ;-;

 

I believe you can do this:

Code:

/summon ArmorStand ~ ~ ~ {Invisible:1b,Equipment:[{id:"planks",tags:{variant:birch},Count:1b},{},{},{},{}]}

 

Thanks, but I already found a way.
