Pool Volume - oval with hopper and safety ledge

does the pool calculator volume calculation for oval pools take into account a hopper bottom with safety ledge? Our 19x43 inground came with the house 24 years ago and I have no idea who the manufacturer is.

Thanks - I have been lurking for years, never registered because my questions have not been new, but this spring I am having a dickens of a time to get the search function to work and scrolling through all the posts to find things has become overly time consuming so I thought I would register to see if search works better.
