ACS Data for Portion of School District within County?

Hello,

Is there a way to get ACS data for the portion of a school district within a county? 

In general it seems that there may be a bug in selecting this "pseudo geo" in data.census.gov. After picking the "School District (Unified)" geography, I am able to select "County" under "Within other geographies" but within the county it appears to give me a list of voting districts (?) that don't have any data associated with them. 

I am assuming this is just not available for ACS data but I was teased by it appearing to be an option in data.census.gov.

Thanks!
