Add custom text at end of reference

Hi,

Using endnote x9, windows 10, word 2016

I would like to add text at end of a reference for foreign language manuscripts.

example

References

Dunkerly, J. (1920). Fish Myxosporidia from Plymouth. Parasitology, 12(4), 328-333.

Nemeczek, A. (1922). Über Zschokkella rovignensis spec. nov. Archiv für Protistenkunde, 45, 390-400. (in German)

How can I do this?

Thanks
