Tool that Tells You how much each layer is contributing to the File Size

I dont think this tool or feature exhists, but if it does, can someone tell me? Or if a version of this exhists, that would be great to know about. I struggle so much with trying to save large files into shared folders with my company's VPN while WFH. I have to play around with deleting certain swatches that I created that I think might be too large or deleting brushes I dont need and then rasterizing vectors (pulling a copy of them to the side of the artboard obviously) to make the file small enough not to consistantly crash illustrator. Even my IT dept has struggled to help me figure out better ways to reduce the file size. 

I want to know if a program/tool/feature exhists that is laid out like the layers panel, but tells you how much each layer is contributing to the size of the file I am saving. That way, I can pinpoint exactly where the issue is and figure it out from there. I work in clothing design and will sometimes have like 20 prints created in the swatch palette or like 40 different brushes being used and have no idea which one is the heaviest or which one is causing the issue. Is this making sense? Does anyone know of anything like this?
