-#### Design considerations:
-
-**Aspect: How the command input is structured**
-
-* **Alternative 1 (current choice):** Chooses the student index from a list of students in the event.
-    * Pros: Easier for TA to refer to.
-    * Cons: More difficult to implement as student index reference needs to be changes.
-
-* **Alternative 2:** Choose the student index from the list of students in the student tab.
-    * Pros: Easier to implement since same student index reference can be used.
-    * Cons: More troublesome for the TA since changing of tabs needs to be done to find the student index.
+#### Possible Updates
 
+Support could be added for the command to take in more student index fields, so that the TA may delete multiple students at once without needing to keep re-entering the same command.
