[suggestion] add \cites to latex_env for multi-citations with page references

[adrien-perello]

What I'm trying to do?

cite several papers at once and mentioning the pages referenced

What is the problem?

\cite works really well as long as I don't need to add the pages

When wanting to add the pages, I should use \cites (ex: \cites{ref1}[2]{ref2}[3]{ref3}[4]{ref4})
But \cites is not supported

And if I use \cite instead, it is read as a single citation

Solution proposed

Include support for \cites
