[e.k.]

The suggestion works well with individual files (pdf), but how to merge files to a song, if the wanted "extension file" is generated by csv-import?

I can select the "leader-file" (I want to extend) as described above. Doesn´t matter if it is a single pdf or imported by *csv.
But if I´m going to add an "extension file", which is imported/generated by csv, I just can import the whole pdf,
from which the wanted "extension file" is generated. I can´t find any way to import just this single "extension file".

Of course, it is possible to select the wanted pages of the whole pdf, mean´s reduce the whole pdf to the wanted file,
but it´s a little bit tricky (to search the wanted pages in the whole pdf.....)

Is there an easier way?

thx in advance,
e.k.
