Unable to see completed view layout in Android Studio

I am creating a vertical LinearLayout that will be displayed in a vertical ScrollView. I can't find a way in Android Studio to see the portion of the LinearLayout that is below the bottom of the ScrollView. Is there any way to see the full layout rather than constraining it to the viewport provided by the renderer?

Like Drew said, creating a user defined device definition has been the only solution which worked for me. Below i show you the steps to follow:

Step 1) Within the preview-pane, open the Virtual Device Selection drop-down and select Add Device Definition..

Step 2) Within the Your Virtual Devices dialog click the Create Virtual Device button.

Step 3) Within the Select Hardware dialog click the New Hardware Profile button.

Step 4) Within the Configure Hardware Profile dialog specify (f.e.) a Resolution of 720 x 4000 px and a Screensize of 12 inch. Also setting the Screensize results in a density of xhdpi (thanks to Mete).

Step 5) Close all dialogs and restart Android Studio. Step 6) Open the Virtual Device Selection drop-down. The new user defined hardware profile can be found under Generic Phones and Tablets.

I've just discovered how. You need to create a user defined device definition in Android AVD - I created one that was 480 x 4000 pixels. Exit and restart Android Studio and then you can select this device in the preview renderer and can see 4000 pixels worth of LinearLayout.
