Is there a way to edit a solid that has been created as a result of a Boolean operation (Add or Subtract)?

Set-up:
1. I create a truncated cone with a bottom diameter=1.0 and a top diameter=0.5 and a height=2.
2. I create a cylinder of height=0.5 and a diameter=1.5. This is positioned under the truncated cone.
3. I use Menu>Modify>Solid Booleans>Add Solid to create a new solid as the sum of the cone and the cylinder.

How can I go back in and edit the top diameter of the truncated cone to change it, for example, from 0.5 >to> 0.75 ???

The deep selection doesn't seem to expose the constituents of the Boolean Add Solid.

I have noticed that if I am subtracting a cylinder from another object (to create a hole) and I retain the subtracted cylinder, then I can edit the retained cylinder and it is linked to the modified object.
But, I don't see a way to edit or retain the objects of a Boolean Add?

Thanks

If you construct cones and cylinders as skin solids between circular profiles or as polygons lathed about their axes, the solids are associative to the profiles. Edit the profiles and the solids update to reflect the change, through most subsequent booleans and utility edits like blends, holes and bosses. Construction using primitives like cones, circles, blocks etc, limits the features that can be edited, especially within agglomerated constructions (booleaned objects) and assemblies.
The same applies to other shapes: blocks, are more flexible if they're created as associative solids or surfaces, like extrusions or sweeps of profiles.
