Preview Customisable Elements (Statements, Portal, etc.)

Since we're not all students, we can't see the outcome of some of the settings we change unless we look at a student's account. Currently, we have to make any changes we're thinking of implementing, and then view a student's information, and if it's not as expected, repeat that process for each change that needs to be made. It would be really great to be able to see a preview while you're making changes to your settings so you know how things are going to appear. For example, while selecting elements for how Statements and Receipts appear, seeing a preview that updates as you tick and untick things.
