Create a new Building Block

Question

Is there a way to add a new building block that says:
<$chapalpha> Chapter Alpha
Currently, I'm using a set of templates that have <$chapnum> that automatically numbers chapters.
There is also a <$volnum> to automatically add volume numbers.
I would like to create the <$chapalpha> building block to automatically create letters (A, B, C, etc) to go with the <$chapnum> building block.
Would it work to use <$chapnum><$chapalpha> to create a 9A module number. This would be the AutoNumber Format for my CT ChapterTitle paragraph tag.
Will this work?

Dennis,
Per your other thread on this... <$chapnum> and <$volnum> are system variables. You cannot create a system variable, but you don't have to in order to do what you want. Just use a regular alpha counter in combination with the <$chapnum>.
Use one para tag to set the Chapnum 9, 10, ... and a second to set the alpha number with a numbering string of C:<$chapnum><A+>.
