if by Link you mean the link list you get with /links ?
then what you are looking for you will have to script your way out through, using customised window and getting links result in your window and choose which option you want on mouse click.
the reason you get all those options with right click is that mirc has to show all the possible options avaiable ...
if you cant script, there might just be some scripts already availble with this feature .. just a guess so try searching the web
