Block Edit Undefined Blocks

[MetalliCAD]

I have some files that were translated from that "other" cad platform and now I have a slew of undefined blocks (*U57, *U137 as examples). The Block Edit command does not work on undefined block names so I have to use the Edit Block in Place routine to set all of the geometry to layer 0 and everything to by-layer which is quite tedious. All of the lisp routines I have found thus far do not work on these undefined block names. Anybody out there have such a beast they would not mind sharing?

Those are anonymous blocks.
I have not tested this, but here is one that claims to work.
