Is there a way to create an exportable renderTarget by code/blueprint?

I need to create a series of sceneCapture2Ds to capture different parts of a scene so I can export them out of UE.

I need a way of creating the RenderTargets for those in a way I can access them later and export, even if only during paused.

if I create a render target using blueprints, as shown below, the editor shows an empty target on the SceneCapture.

is there anyway to create a renderTarget I can export using code or blueprints? I need to capture a huge number of images, so creating them by hand is impossible.

Thanks in advance!
