Material-ui: Overriding MuiInputLabel outlined shrink

[GavMan1995]

It would be useful to be able to edit _outlined/filled input label on shrink_ in the global theme overrides!
ie.

export default createMuiTheme({
  overrides: {
    MuiInputLabel: {
      shrink: {
        outlined: {
          transform: .... etc.
        }
      }
    }
  }
})

or like

export default createMuiTheme({
  overrides: {
    MuiOutlinedInputLabel: {
      shrink: {
        transform: .... etc.
      }
    }
  }
})

@GavMan1995 If that can help:

import React from "react";
import PropTypes from "prop-types";
import { withStyles } from "@material-ui/core/styles";
import TextField from "@material-ui/core/TextField";
import { purple } from "@material-ui/core/colors";

const styles = theme => ({
  inputLabel: {
    "&.focused": {
      color: purple[500]
    },
    "&.shrink": {
      backgroundColor: "grey"
    }
  }
});

function CustomizedInputs(props) {
  const { classes } = props;

  return (
    <TextField
      InputLabelProps={{
        classes: {
          root: classes.inputLabel,
          focused: "focused",
          shrink: "shrink"
        }
      }}
      label="Custom CSS"
      variant="outlined"
      id="custom-css-outlined-input"
    />
  );
}

CustomizedInputs.propTypes = {
  classes: PropTypes.object.isRequired
};

export default withStyles(styles)(CustomizedInputs);

you can use

    MuiInputLabel: {
      outlined: {
        '&$shrink': {
           transform: 'translate(0px, 0px) scale(0.75)',
          },
      },
    },
