[AccessD] Trimmean Function in Excel - How to in Access

I'm trying to trim my dataset in Access so that I drop the top 10% of the 
data as well as the bottom 10% of the data so that I can get rid of 
extraneous values that may skew the results.  I know that in excel, I can 
use the trimmean function to do this.

Can't find an equivalent in Access.  Any Suggestions?
