If you're an enterprise user you can choose a custom style to be the default style in your organization.
Log in to the Members Area of the Intelligent Editing website and open the 'Style Manager' tab.
Scroll down to the list of uploaded styles at the bottom of the page. If you have not already uploaded a custom style to the Style Manager, you will not see this list. Find out how to upload your style here.
Click the radio button in the 'Default' column for your chosen default style.
Download your custom installer package (instructions can be found here) and install PerfectIt using the CMD to apply your default style settings to the installation. When users start up PerfectIt, the chosen style will be automatically selected.
