No.

Some sites
I've researched say yes, others say no. If no, what are the options

replacing the whole circuit breaker panel?

Get a bus bar kit from your distributor. Install in panel, there will
be predrilled/ tapped holes for this. Connect regular bus bar and
added bus bar via the larger set screw holes intended for this
purpose. Use short section of #4 or #6 bare copper to connect. Should
take half an hour and cost under $20. HTH

Thanks, Joe. That's what I thought when I saw the two front-facing threaded
screw holes on the frontmost bar. At first I thought they were empty
set-screw threads but on closer inspection, that's where two existing bus
bars are connected. I'll check with the local supply house after I record
the box model number and take some photos to show them. I recalled reading
somewhere that two wires to a hole can lead to intermittent neutral problems
and that's why I asked.
