When you tick Allow individual marking sheets in the competition settings, riders in the same competition can ride different tests, each with their own marking sheet. Setting the sheet for every start meant scrolling through one long list of every marking sheet in Equipe, more than 2,400 of them. That is much quicker now.
The individual marking sheet cell in the start list now works like the rider and horse cells. Click it, or move to it with Tab or the arrow keys, and start typing. The list narrows as you type, and you can leave out the accents, so "kur" finds Kür.
The sheets already used in the competition come first, with the number of starts on each. The federation and type filters from the competition settings are at the top of the list, and they stay as you set them while you work down the start list.
Enter picks the sheet and moves on to the next rider, so a whole start list can be done without the mouse. To remove an individual marking sheet, delete the text and press Enter.
