Cheaper then a new saddle is anti-chaffing cream.
I also have some shorts with more definite seat bone pads that lift you off the sensitive areas.
Otherwise, it sounds like you might want to try a saddle with a front area recess or cut-out?
Good luck.
Let us know what works....I still get some soreness on longer rides and worry about the back to back long days of the next enduro ride I have planned - and I use all 3!
