LyX ⇒ multiple bibliographies using Part*

[nardis_miles]

I have installed lyx 2.3.3 on ubuntu 18.04. I need a bibliography in the main body and one in each appendix. I have built a test document where I use per part in the Document --> Settings --> Bibliography menu. I am using biblatex and biber. Also, I have inserted a Bib(la)tex bibliograhy in each part. If I use actual parts (Part instead of Part*) everything works as advertised. However, I don't want part labels. Part* would seem to be the answer. However, this just produces two copies of the same bibliography. Is there a way to use this? I need to follow ANSI standards.

Thanks,
