that will bloat the already large tuc file, so here is an alternative (i bet you can find where to patch):

strc-ref

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0local external =3D struc.references.colle= cted -- direct references
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0local lists=C2=A0 =C2=A0 =3D struc.lists.= collected=C2=A0 =C2=A0 =C2=A0 -- indirect
references (derived)
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0local pages=C2=A0 =C2=A0 =3D struc.pages.= collected=C2=A0 =C2=A0 =C2=A0 -- pagenumber data
local sections =3D struc.sections.collected

and

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0if prefix =3D=3D "" then
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0prefix =3D name -- this can clash!
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2= =A0 =C2=A0 =C2=A0end
local section =3D references.section
if section then
=C2=A0 =C2=A0 =C2=A0if sections then
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0references.sectiondata =3D sections[secti= on]
=C2=A0 =C2=A0 =C2=A0else
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0-- warning
=C2=A0 =C2=A0 =C2=A0end
end

strc-pag:

=C2=A0 =C2=A0 =C2=A0local sectiondata =3D references.sectiondata or
sections.collected[references.section]
=C2=A0 =C2=A0 =C2=A0if not sectiondata then
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0return entry, false, "no section dat= a"
=C2=A0 =C2=A0 =C2=A0end

there might be a few more such places where we can bind to the loaded data<= br>
