Placed Drawing of PMK, References Source File Path, Instead of Host File Path in Auto-text

[Josh Verran]

I have an "Ancillary" file (PLN), which houses all our titleblocks, guidance notes, etc.
The Titleblocks are published as PMKs. Export options are set to keep autotext dynamic, in lieu of Baked.

The PMKs are then placed as drawings in our template and therefore every project file.

All the autotext displays as expected (eg Layout Name, Transmittial ID, Project Info etc).

However, I've only just noticed that the File Path references the PMKs file path (Source), not the file that has the PMK (Host).
It's not a biggie, but wondering if this is perhaps a bug.
