Aura art/buff troubles

Is there a way to make the art for an aura's buff be displayed on the bestower of the aura? For example, when a paladin learns "Devotion Aura", the blue circle things appear around all units around him, but not the paladin himself.

Is there a way to change it so that the circles would be around the paladin also?

Yes, I know I could use the "Art - Target field" as that art, but in my case I can't; I have 6 different art effects (1 for each level of the spell) which need to be displayed individually.

I know I could also use the "Slow Aura (Tornado)" thing and attach effects to the hero, but I would rather not do that because I need to change the effect when need-be in a trigger that runs every 0.20 seconds and affects every unit on the map. I figured adding/removing abilities would be very system-intensive, so I hoped to eliminate the worry by simply setting the level of the ability to the correct level to display the correct art. However, the art does not show up on the unit.

This brings me to my second question: Is there a way to remove a specific buff from a unit? The way this works now, the ability level is updated, but the buff from both levels is present for a second or so because of the aura refresh rate. Normally, this wouldn't be noticable, but the effects I'm adding to the units are different colorations of the same model, which would look bad. Can I remove just a specifc buff?

The Art - target field can stack effect just use "add model" it should work

call UnitRemoveAbility(unit,buffid)

Dang! I thought that wouldn't work because of everything else you can't manipulate about buffs, as I asked about recently.

You're saying that if I put 6 different effects in there, they would be displayed in order depending on the level of the ability?

no it will display all model at all level.But obviously i didn't understood your question.
