custom hero units having reg. unit abilities

I'm tired of the hero arena maps and stuff having the same old hero abilities displaced into diff. units. Is there a way that I can give a hero say, Custom Jaina Proudmore or Custom Orc Warchief, learned abilities such as Stasis Trap, Bloodlust, Raise dead (necromancer ability)? I'm sure there is a way to do this, and it's either really freakin easy, or fiendishly hard, either way, i would really appreciate prompt response, I'm sittin on the edge of my seat.

Yes, instead of hero abilities, just use abilities in the unit editor.

Yes, i did that in my hero arena. The latest version is called Nucleus' Hero Arena Legacy 5.00 and has 34 heroes. Besides the normal heroes they are all custom and perfectly balanced (no kains), and the map is pretty clean too. I'll upload it some time.
