Multiple successes and failures when rolling above and bellow a target number by a certain amount?

I'm trying to make a macro for a game I'm designing. In it if you roll above a target, you gain a success, and every 2 higher than that target number, you gain another success. If you roll under it, you get a failure, and every 2 lower, you gain another failure. Is there a way to build this into a macro? Sorry for the overlong tittle >-> i'm kinda late and stressed so it's hard to be brief.

It might be possible, if you can accept failures being reported as negative successes, but it depends how the rounding is done.   If the target is 6, what are the results for each of the following rolls: 3, 4, 5, 6, 7, 8, 9 ?

I can deal with not accounting for failures, cause that'll be more on the GM side. Mostly want it to be easier for the players. Your supposed to count down from the target number to your result. 0 successes can just represent a fail? -1, -1, 0, +1, +1, +2, +2
