Configure shell escape output directory

I have a bunch of standalone files which require shell escape to build. Following the guidance here, I added the option -shell-escape to pdflatex. However, my custom output directory

  "latex-workshop.latex.outDir": "%DIR%/.tmp",

does not appear to extend to shell escape mode. I tried to manually set the output directory as shown below but without success.

  "latex-workshop.latex.tools": [
    {
      "name": "latexmk",
      "command": "latexmk",
      "args": [
        "-synctex=1",
        "-interaction=nonstopmode",
        "-file-line-error",
        "-pdf",
        "-outdir=%OUTDIR%",
        "-pdflatex=pdflatex -shell-escape -aux-directory=%OUTDIR% -output-directory=%OUTDIR% %S",
        "%DOC%"
      ]
    },
  ]

How can I get the output of standalone files to end up in latex-workshop.latex.outDir?

Please post a MWE along with your configuration to see if we can reproduce the issue otherwise we may both waste our time not speaking the same language.
