editing Debug Information Directory in a PE file

[jonwil]

I have a PE file and a matching PDB file.
Problem is, the PE file was packed and somewhere the packer (or the unpacking process) has removed the debug information directory that points at the PDB file.
Which means that (AFAIK) IDA cant read the PDB file.

Is there a way to add back the debug information directory or to get IDA to load the PDB file without it?

I am sure the PDB file matches because I dumped some symbols from it with pdbdump and I can match them up to ASM in IDA.
But I dont want to have to manually input all these symbols if I dont have to
