Does `Property` path syntax supports casting in Avalonia, like in WPF?

Often in WPF we need to cast property to specific type to be able to access further properties in the path, e.g. from some answer:

Storyboard.TargetProperty="(Ellipse.RenderTransform).(TranslateTransform.X)"

Here we cast Ellipse.RenderTransform to TranslateTransform first, so that we can specify X as a target property.

How can I do the same in Avalonia to target e.g. control's Effect property?

Here is what I want:

<Grid><Grid.Effect><BlurEffect Radius="0"/> <!-- I want to access Radius --></Grid.Effect><Grid.Transitions><Transitions><DoubleTransition Property="(Grid.Effect).(BlurEffect.Radius)"                              Duration="1"/> <!-- AVLN:0004 - Internal compiler error while transforming node XamlX.Ast.XamlAstXamlPropertyValueNode: Avalonia.Data.Core.ExpressionParseException: Expected end of expression. --></Transitions></Grid.Transitions></Grid>
