Set in-editor camera to specific resolution?

Hi there, I noticed that the in-editor preview of the orthographic camera I’m using does not show what I see in the packaged version of my project on Android:

Setting the camera to “Constrain Aspect Ratio” produces black bars in my packaged Aandroid build that are not visible in the camera preview in the editor.

Unchecking “Constrain Aspect Ratio” removes those black bars on android but I get a square camera preview.
With the black bars removed some bits of the level that should be hidden are rendered, however.

Is it possible to set the camera preview to show exactly what I would see in the packaged build?
