Help cross-referencing two autonumbered series

[James Dyson]

Hello all,

Does anyone know how (or if) you can make a cross-reference when two or
more autonumbered series are used?

For example: I want the cross reference to read: 
see Step2c on page 9
I had been using see Step c on page 9 (for example this is formatted:
Step <$paranumonly>\ on page <$pagenum>) or Step 2 on page 9, but I need
to consolidate in one cross reference. Can anyone help? I am using the
following autonumbering formats in my paragraph designer. 

You'll see I use two different letters for the two different numbered
series.
For the parent (Step2 in this case)
D:Step <n+>

For the child (c. in this case)
T:<a+>.\t

Thanks,
James
