Software to work alongside Articulate

Hi everyone, 

My company is currently in need of a task management/LMS tool that is compatible with the Articulate suite but we are having trouble identifying the correct terminology and product.

We have a two-week new hire program that we would like to house in this software in order to do the following:

• House content (courses, training documents, videos, etc.) 
• Provide a checklist for tasks to ensure visibility to the learner, mentor, and manager (we would like to do this outside of a user license model since the learner will only be in the system for 2 weeks)
• Prompt acknowledgments of task completion (i.e. "By entering your electronic signature here you agree that you have...")
• Provide reporting that helps the training team identify potential knowledge gaps or areas of opportunity. 

We have looked at task management systems (DropTask, Flow, Wrike, etc.) and landing page software (Zoomforth) but are not finding the right fit. Does anyone happen to have a suggestion of what we could use?

Many thanks in advance!
