I remade my interactive pit map for houston in Google Sheets for Detroit.
You can enter in team numbers to highlight them in yellow, or select a division and enter a match number to highlight teams in their respective alliance colors.
It’s currently running on Houston’s schedules, I’ll get that updated as the CSVs for Detroit’s preliminary matches get posted.
It looks like all the prelim schedules made it through except for Curie, which has been updated to the schedule on The Blue Alliance. This means that if you’re from Curie and you’ll already made a copy, you’ll need to make a new copy in order to have the match schedule update.
