Hello,
You cannot see functional option itself in the user interface. It does not have UI form. You can see a constant or any other object that is used as a location for functional options. By changing this location object you can apply functional option behaviour.
For you second question just go to object class in configuration tree, open change/setup wizard and go to functional options tab. Then click against each of the functional option that you want your object to be linked to.
Hope this helps,
Kind regards
Alex
