If I understand this correctly I think the problem is you want to check for and add something to an item on one line for which the value is only provided in the next line. Only two approaches I can think of right now: reverse processing lines (tac) or grepping with line numbers. If you need an example please post more lines.

colcrt
COLCRT(1) BSD General Commands Manual COLCRT(1)
NAME
colcrt -- filter nroff output for CRT previewing
SYNOPSIS
colcrt [-] [-2] [file ...]
DESCRIPTION
The colcrt utility provides virtual half-line and reverse line feed sequences for terminals without such capability, and on which overstrik-
ing is destructive. Half-line characters and underlining (changed to dashing `-') are placed on new lines in between the normal output
lines.
The following options are available:
- Suppress all underlining. This option is especially useful for previewing allboxed tables from tbl(1).
-2 Cause all half-lines to be printed, effectively double spacing the output. Normally, a minimal space output format is used which
will suppress empty lines. The program never suppresses two consecutive empty lines, however. The -2 option is useful for sending
output to the line printer when the output contains superscripts and subscripts which would otherwise be invisible.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colcrt as described in environ(7).
EXAMPLES
A typical use of colcrt would be
tbl exum2.n | nroff -ms | colcrt - | more
DIAGNOSTICS
The colcrt utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
col(1), more(1), nroff(1), troff(1), ul(1)
BUGS
Should fold underlines onto blanks even with the '-' option so that a true underline character would show.
Can't back up more than 102 lines.
General overstriking is lost; as a special case '|' overstruck with '-' or underline becomes '+'.
Lines are trimmed to 132 characters.
Some provision should be made for processing superscripts and subscripts in documents which are already double-spaced.
Characters that take up more than one column position may not be underlined correctly.
HISTORY
The colcrt command appeared in 3.0BSD.

July 31, 2004 BSD
