Welcome back Zettacorn :)
There isn't an editor that can add them yet, or at least that I know of. The hex for these stats is handled differently to normal stats so its harder to get. Just recently Goodlookinguy has figured out how to generate the hex for these addons. You can find 1291-1310 in this post.

He is going to include this in his latest release of his hex data generator when its finished.
Now I can tell you how to generate the hex for these addons. This will be included in my hex data guide when I finish it.
Lets start with pierce. I am going to add it to Sakyamuni's Light. I have my base hex data which is slightly modified already.
Code:
0100ff00010000000000010010270000102700002c00040c61006400610066006400660000000000240100000a000000000000004a010000ee0100008e02000013030000070000000000404000000000010000000000000000000000

Now I am going to find the number addons and increment it by 1.
Code:
0100ff00010000000000010010270000102700002c00040c61006400610066006400660000000000240100000a000000000000004a010000ee0100008e02000013030000070000000000404000000000010000000000000001000000
Now I open my elements.data and I find ID 1275.

I am interested in two things in the elements, the ID and Value 1.
I pop 1275 into my hex converter (I use pwgen1 from Romulan's Tool pack).
I get
Now here is the important part. You must change the 0 to a 2. Your code should look like this.
Now we look at Value 1. This is 141. We put this into our hex converter and get;
We add this to the code we generated for the ID.
This is the hex code for pierce.
Lastly we add it to end of our hex data for our Sakyamuni's Light.
Code:
0100ff00010000000000010010270000102700002c00040c61006400610066006400660000000000240100000a000000000000004a010000ee0100008e02000013030000070000000000404000000000010000000000000001000000fb2400008d000000
The blue is the number of addons we changed earlier and the red is the hex data we generated.
Result.
