Yes, and please see below.

To do this, just modify your existing pattern to find successive pairs of
matching lines and combine their contents:
Find: (\d{6})(.+)(?:\r\1(.+))
Replace: \1\2\3
and then repeatedly apply Replace All until all line pairs which start with
the same numeric prefix have been consolidated to single lines.
(E.g. for groups of 16 lines or fewer, this will take at most 4 passes of
Replace All; for groups of 64 lines or fewer, 6 passes; etc.)
PS: John Delacour's text filter is a much nicer general solution; the only
advantage of the above is it doesn't require knowledge of Perl.
