PhpStorm ExpectedValues/expectedArguments array auto-complete

Question

Is it possible to use the ExpectedValues trait or the expectedArgument() meta directive to hint the possible values in an array?

My use-case is a function that accepts either an array or a string:

function check(array|string $checkable): bool
{
    if (!is_array($checkable)) {
        $checkable = [$checkable];
    }

    foreach ($checkable as $item) {
        if (!in_array($item, ['value1', 'value2', 'value anything'])) {
            return false;
        }
    }

    return true;
}

Here I wanted PhpStorm to auto-complete with the values in the array (['value1', 'value2', 'value anything']) when I use the function, both when passing an array of values and a value directly.

For just a single value this is already possible using #[ExpectedValues()] or expectedArguments().

function check(
    #[ExpectedValues(values: ['value1', 'value2', 'value anything'])] array|string $checkable
): bool

But when passing an array it does nothing.
