+
+The **Submit All with Placeholder** feature is a utility within the Bulk PDF 
+Upload interface. It allows instructors to automatically submit an empty 
+"placeholder" submission for every active student on a specific gradeable. 
+
+An example of when this would be useful is for an assignment (like a presentation) where students do not have anything to submit to Submitty, but the instructor still wishes to grade them through Submitty.
+
+In this case, an instructor can use the Submit All with Placeholder feature to enable rubric grading for all students. 
+
+---
+
+## How to Use this Feature
+
+1. **Create the Gradeable:** Ensure your gradeable is set to the 
+   type: *"TA/Instructor will (bulk) upload scanned .pdf"*.
+
+2. **Access the Submission Page:** Navigate to the gradeable's submission 
+   page and click the **Bulk Upload** tab.
+
+3. **Click "Submit All with Placeholder":** This button is located 
+   near the top of the Bulk Upload section alongside the other submission modes. 
+   ![](/images/instructor/assignment_preparation/placeholder_submissions.png){:width="800px"}
+
+> **Important:** This action **will** create 
+> a new submission for all students on the gradeable. It will appear as the student's
+> active version within the grading view and on the database. It will not erase any 
+> previous submissions.
+
+---
+
+## Grading
+
+Once the placeholder submissions have been generated, they can be graded like any other student submission. They will be listed as a new version under the student's version status. Further uses of the function (while uneccessary) will simply increment the version number.
+
+---
+
+## Troubleshooting
+
+Ensure you are logged in as an Instructor level user.  
+Full grading access is required to use this feature.
