I know, even with a full synthetic and I do, BUT can you make a filter last 
 longer?

You  should change your oil annually, regardless of mileage.
There are things in  oil that are activated by heat and only last about
a year, or so I'm told  by a guy who knows oil.
Maybe you are using something different or I'm ill  informed or my info
is outdated.
A wise man welcomes correction so  please correct me if I'm wrong.
Cheers,
