Bulk edit library links to map database library

I’m wondering if anyone had the issue to map all symbols of whole schematics to database library parts in order to update fields from a database library.

I found this but it seem to be no real comfortable bulk editing like the symbol fields table as this is very error prone to do with complete bom:

Then I tried KiField - this is great!!! but doesn’t export/import the symbol library link (perhaps easily editable?).
“Edit Symbol Library Links” tool doesn’t help because the schematics use many generic symbols that I have to split into different IPNs.

Are there any ideas? Once I imported an old Eagle lib and worked a lot with Notepad++ and its Regex-Replace over full folders to uniform line widths, text sizes, etc. With caution and detailed diff that worked nicely. Now as I’m not that used to py scripts I tend to use the regex method once more. But perhaps there is a nicer more repeatable way for more than one schematic :grimacing:.

(I’m on latest v8 and checked in latest v9 if there is something doing the trick & willing to update soon)
