The county name is not given by default. You can, however, force MTPE to
include it by making County one of your ballot styles (or the only one if
you do not want House, Senate, etc... info in your street index). To make
County a ballot style, choose P&E Mgt-Settings,
click on the Ballot Styles tab, and Add the County layer (click OK to save
the new settings and close the dialog box). Be sure to run P&E
Mgt-Update Ballot Styles before doing the street index so the
street index option Precincts and Ballot Styles is not grayed out.
