Is there a way to add a tag to a LaTeX document? Something that allows one to omit it from mass compilation?

Say I have three .tex files, formulas, math-notes, and artwork.

Would there be a way to tag them as follows, for example,

formulas.tex -> math, graphics

math-notes.tex -> math

artwork.tex -> graphics

such that I could ask LaTeX (pdfLatex specifically) to compile only the documents with a certain tag? e.g. pdflatex --tag math .* would compile only the formulas and math-notes in that directory into one pdf.

I know you can do this manually by simply \includeing certain files in a new .tex file, but is there a way to automate this in a way that the command line LaTeX understands, so one could compile many files at once?

    You might want to look at the multiaudience package, the audience can be set using \jobname to make it controllable from the command line. – Marcel Krüger Jul 01 '21 at 19:01

    which files you latex isn't something you control from latex but from your comandline or IDE. for example if all your math-notes documents have notes as part of their filename then for i in *notes*.tex; do pdflatex "$i"; done would latex them all – David Carlisle Jul 01 '21 at 19:10
  • @DavidCarlisle even easier if latexmk is there latexmk -pdf *notes*.tex – daleif Jul 01 '21 at 19:17
  • @DavidCarlisleSimilar to how I tagged this stackexchange post so people could sort and find it, I'm sure you can tag PDFs. So, if it is at least possible in LaTeX, I would like to know how. Furthermore, understand that I want these to be compiled into one PDF, so LaTeX becomes more relevant. Ideally I would be able to selectively include documents (literally with the \include command), but any documents without the tag would not be included. Like I have some sort of \includetag{math} command. – KNOB Personal Jul 02 '21 at 11:13
  • @MarcelKrüger That looks exactly like what I was looking for. That's so funny how perfectly it matched my expectations. In cases like these, where the de facto answer is in a comment, what should I do? – KNOB Personal Jul 02 '21 at 11:19
  • @KNOBPersonal one way of resolving the question would be to close as a duplicate of a closely related one, such as https://tex.stackexchange.com/questions/359656/different-pdfs-from-one-tex-file/359696 or https://tex.stackexchange.com/questions/266117/1-compilation-several-outputs/266682. Another way would be to ask Marcel Krüger to write an answer here. A third option is to close this question with the custom reason 'solved in comments'. – Marijn Jul 02 '21 at 12:22
