You should be able to define all of them in same option (provided they are same size) or click on the pin in the property manager and then you can quickly assign the bolt connection
One thing that has helped me is creating a library for various bolts. Define a bolt connection and save it in a library. Next time you want to define a bolt connection, just drag and drop and select the bolt/nut head circles. You don't have to fill out preload and other data everytime.
Hope it helps.
