Userform Combobox - Choose Multiple Items from list and input on seperate lines

Attached Example
Right now the user chooses item from list and info is added to the first open line.
Is there a way to allow the user to choose first third and tenth (random items from list) and have them fill in starting with first open line (and leaving no blank lines)

Bump - Anyone know how to do this?
Replace the combo box with a list that can be ticked off, or selected. And each part would add to the next open row...
