Block Group level data

Hi ACS folks,

Could you please help with this question. When working with say a Total Population (b01003) table and choosing Geography, how could I choose a Block Group level and go across all counties in a state? It seems too cumbersome to have to download data county by county in a state like Texas, especially when I need some 35 tables.

Thank you very much for any help!
