Any way to tweak Sweep option -> ends?

Hi

Does anyone know if it is possible to tweak how aggressively MOI forms the pointy ends if you select that option when performing a sweep?

I like the merging in effect, see 'cowlings' on attached image, but it would be great to have it apply more gradually or restricted more to the end region.

Thanks
