Hi there, @MichelleColburn ...
I think some more information from you will be helpful. What kind of presentation are you wanting to create? Since you posted this question within the Canvas Studio discussion area here in the Community, are you wanting to use Canvas Studio to record a screen recording presentation and submit it as part of an assignment to your instructor? Or, are you wanting to create a presentation (using something like Microsoft PowerPoint) and upload that PowerPoint file to your assignment submission?
If you could provide some more details for us here in the Community, then we can provide more help on what you can/cannot do within Canvas.
Thanks Michelle...looking forward to hearing back from you soon!
