Is it possible to use Nik filters in Lightroom successively like the smart objects in Photoshop?

Let me give an example … in Lightroom … let’s say I added SilverFx on a DNG photo with a control point … and then I added Sharpener Pro layer on the BW photo created with SilverFx and made some adjustments in Sharpener. After adding Sharpener layer, is it still possible to tweak the control point added with SilverFx?
