How to typehint an intermediate value in chained code using PHPDoc

I have the following code:

$id = $ui->getWidget('import_id')->value;

I know the class type of $ui. The getWidget() method can return one or more types of widget classes based on the parameter passed in. Some of those widget classes have a value parameter, and some don't.

If I want to add a doc hint to say "I know what this particular value of getWidget() is returning", can I do that without splitting up my code? i.e. I know I can accomplish this by adding an intermediate variable, e.g.:

/** @var KnownClassWithValueProperty $idClass */
$idClass = $ui->getWidget('import_id');
$id = $idClass->value;

But ideally I'd like to not do this, but somehow type-hint the value of $ui->getWidget('import_id').

Thanks!
