If there is only one outline-numbered list in the document, using LISTNUM
fields in conjunction with that list is very easy. Just insert the field
where you want the number:

1.0 Level One (applied via a style)

__        { LISTNUM \l 2 } Text of level two

You can insert the field manually, by pressing Ctrl+F9 and typing the field
code as shown ("l" is lowercase L, and it stands for "level").
Alternatively, you can use the Field dialog box, selecting the desired level
for the list item.

You can change the level of an existing field by right-clicking it and then
choosing Increase Indent (or Decrease Indent) from the context menu.

Field codes: ListNum field

{ LISTNUM ["Name"] [Switches] }

Inserts a set of numbers anywhere in a paragraph. LISTNUM fields can be
incorporated into numbering from a simple or outline-numbered list.

Instructions

 Name
 Associates a LISTNUM field with a specific list.
 To emulate the AUTONUM, AUTONUMOUT, and AUTONUMLGL fields, use the
NumberDefault, OutlineDefault, and LegalDefault names with the LISTNUM
field.

Switches

 \l
 Specifies the level in the list, overriding the default behavior of the
field.
 \s
 Specifies the start-at value for this field. This is always assumed to be
an integer.

 > 1.0    First Level - Regular style
 >
 > 2.0    First level - Regular style

 >         2.1    Second Level (without "initial block") - Regular Style

 >                  __       2.2.1.1    Fourth Level
