Actually, the closest thing mechanically to an Astral Distinctive Style would be Astral Impressions, though it's a loose fit. Note that this is SR3, and Data Shadow does not exist.

Wouldn't the negative quality Astral Beacon be what you're looking for here?
If I'm remembering the quality right it gives you the traits of "you are easier to notice astrally and easier to track". That's pretty much verbatim what Distinctive Style gives in the physical realm...
