Change order of toolbar buttons

[mathforum]

I have read everything possible on this topic before it seems as if this has been asked and answered. There are a couple of proposed methods to add/delete buttons but nothing confirmed about moving their positions that has been explicitly defined each step of the way and confirmed by someone, at least not that I found after 2-3 hours.

I'm adding custom BB code and these buttons all end up on the last row, bottom-right. Some of these are directly related to other groups of buttons and should be there. Let's say for example I make a custom BB code for center-justified formatting. I fill out everything correctly, upload the image and it's working fine except for its location.

How can I move it to another area of the toolbar?
