Surface Area Table

[ScotLaunch]

Hi,
For more complex grain geometries, it's sometimes useful to work out the burning surface area progression/regression from a 3D model. Would it be possible to add a feature that would allow the burning surface area to be defined for custom grains by a table of values at n number of points throughout the burn? Realise this is a less elegant aproach than applying the FFM algorithm but could be a good work around for more complex geometries.
Great job with the development so far btw, incredibly useful tool.
Thanks
