Defaulting a lookup value on a page via URL

I have created a pretty standard page with a lookup list that users can choose the main value and the other lists adjust to show values associated with that choice.

Users want to be able to default their choice.   There is no list of users aligned with these choices and it is not feasible to create/maintain such a list.

Is there a way I can provide users with a URL that automatically defaults a choice to a specific value.  For example, if I want to set the default value and displayed items to be Risk Management, I just give them a Risk Management URL that defaults the choice.  I don't care if they change their choice after.

Screen shots below showing how it works.   I don't want to create 80 pages, one for each choice cause you can't share widgets across pages.  Updating 80 versions of the links section would be painful.  Plus 80 different pages, one for each choice is very maintenance heavy.
