The VOR has probably been hard tuned in the rad-nav page if it's on the field, so is displaying itself on the ND? I'd just do what MCDU2 said and just pull hdg and put your green track line running over it on the ND. You can then tidy up the box to give u the extended centreline or whatever you like. Just keep it simple. You can faff about putting in discontinuities and going dir to and keeping it in managed, but you dont want to be heads down in the box drawing green string all over your ND at this point and u don't know where they are gonna send u after the VOR anyway.
