Looking for Canva/Google Slides help-

Our teacher has kids create a single canva or google slides, but then wants to compile them into one giant slide show (either in Canva or Googleslides).

In the past, we had them submit a link to their slide, but then we are downloading each slide and adding them to the master slide show (we don't add the students as editors to make sure they can't delete other people's work...), which works, but is obviously time consuming.

Is there some easier way that I don't know about?

We want the students to be able to see all the student work in the grade in one spot.

My other thought was a spreadsheet or doc just linking to everyones slides. View only.
