If Home Studio works the same way as Vegas Pro does, you can save presets in the Project Properties window.
Load in a file like you usually do. Once you select it in the Properties window, save it as a preset (for example, My Camcorder).
When you start a new project, load your event, go to the Properties tab and select this preset.
In Vegas Pro, you also have the option (bottom of the Properties window) to Start all new projects with these settings if you want to.
