The documentclass revtex4-1 allows multiple citations to appear on the same line in the bibliography. This is accomplished by adding a star next to the citation key [1]:
\cite{bethe, *feynman, *bohr, einstein}
However, can we add stars next to citation keys in LyX's GUI without using ERT (evil red text)?
