Cross Reference help

I am trying to make a cross-reference that takes into account multiple levels of a step and includes those levels in the reference. In the example below I want to add a cross reference to 2. (b). to cross-reference step 1. (a). (3).  But I want the reference to include all of the levels in the reference. So it would say See Step 1. (a). (3). (right now I am only getting the (3). to show up in the line.

1. Blah

    (a). Blah Blah

          (1). Blah Blah

          (2). Blah Blah

          (3). Blah Blah

    (b). Blah Blah

2. Blah Blah

    (a). Blah Blah

    (b). Blah Blah

BTW this board has been awesome in its responses and help.
