Any way to "reverse lookup" a table tag?

[Scuttlebutt95]

I have a drawing (created by someone else) that has multiple sheets.  There is a line table for each sheet that starts with L1 on each sheet - so there are a lot of duplicate tag numbers.  I removed the L1 line from a table (L1 line is not gone, just temporarily hidden as that line may come back).  When I did that I noticed that an L6 line mysteriously appeared in the table.  I don't have any idea what line/tag this L6 is referencing.  Is there any way to find that out?  

I already tried to do a quick select for a line matching the distance / bearing shown in the table, but didn't find what I was looking for.  it's possible that the tag is referenced to a polyline or Parcel segment but there isn't an option to select by length of segment.  

Any ideas?

Are you sure that L6 is not the same as the previous L1?
