Each scene trigger is linked to a single scene only. However, you can achieve the effect of having multiple scenes it a couple of ways.
By using buttons with 'Scene Links' you can allow your users to navigate through multiple scenes on a single trigger. This is useful if you have too much content to comfortably fit in the space available on your trigger.
Consider cutting your trigger into smaller parts and making each of those a trigger. This approach is useful when dealing with magazines, catalogues etc. where it is more comfortable for users to scan items individually, and more convenient for you to manage content when it is linked to single items.
