Alt-cast self cast for all spells

[Bolnica 0]

Hello, I'm looking for an addon or macro that will make all of my alt-casts self casts. As a priest I noticed that only healing spells with a cast time are able to be alt-cast on myself, but what I'd like is to make that work for my PW: shield and dispel magic, buffs, etc. There is the auto-self cast option but it just doesn't fit my gameplay. Any ideas?
