RevTex 4.1 (
https://journals.aps.org/files/revtex/auguide4-1.pdf) has worked in a feature that allows multiple references to be grouped in a single citation by inserting a "*" (star) before a reference that one wishes to be grouped with the preceding reference. For example,
will produce two citations, [1] with A and [2] with B and C. I know that in Lyx 2.1 I can simply insert the above code as LaTeX code. However, I was wondering if this is somehow built in to the "Insert -> Citation..." command in the top menu (since ReVTeX 4.1 is now officially integrated into LyX 2.1). I could not figure out how to do it that way.
Thank you in advance for your help.
