How do I smoothly transition focal distance when blending between view targets?

Im building a configurator and have set static camera positions and I’m blending between them. The blend works fine but the camera settings like exposure and focal length don’t blend, they just change immediately once the blend is complete. Can anyone recommend a good way to have these values lerp over time as the camera position changes?

Ive attached my current camera switching blueprint and would ideally like to fit it in here somewhere.
