how to modify values of automatically generated offMesh link?

hello, i have auto generated some offmesh links for my navigation. however, i am unable to access the auto-generated offmesh links to change things like 'cost override' or 'bidirectional' (i would like for to be able to make my character jump up a large cliff (as well as jump down) by making the vertical offmesh link bidirectional). does anyone know how to access and modify the Off Mesh Link component of auto-generated offmesh links? thanks
