Yes, you can. Customers are allowed to create custom extensions to the SharePointLMS in order to meet a specific set of business objectives.
These custom extensions must be comprised within newly developed scripts or database objects. Customers may choose to develop custom functionality using .NET technology or any various scripting language. SharePointLMS provides a Navigation module that enables site administrators to add custom links to the navigation menu of each user class (e.g. learners, instructors).
Note, that we do not guarantee custom extensions will be supported in newer versions.
