Both the program and betfair site allow you to lay at SP any time during the day. If by the same time you mean the exact same time, no, you'll have to enter each market on the site or via the program ad do each separately.
On the program there's a middle column on the grid saying Projected SP, clicking that column brings up the option to lay or back at SP depending which side of the box you click. If it's not showing on your grid you can select it from the grid options in preferences.
