Hi Johnny,
You can create custom module and under 'User intereface' create a new UI element. Under section 'Element content' you can select 'User control' for type and target URL can be link to you custom .aspx page, like:
~/CMSModules/<ModuleName>/UI/Default.aspx
In that way, you can set up permissions for the app, so that only certain users can do imports.
Best regards,
Dragoljub
