Trimmed attributes

I have a set of images used for Object detection. The annotation is in Pascal VOC format with bounding box for each object of interest. Associated with each object, there are some additional attribute information.
When loading the image set and annotation to the project space, a message popup and say “we trimmed annotations so they are fully in the frame”.

Is there anyway to retain the additional attribute, for example, to have such info shown on the sidebar when an image is displayed.
