Form vs. View dropdowns

I have a small app that takes user input via a simple form. When the form loads it sets the values of a dropdown (the Activity) based on the contents of a table (i.e. the Activities table). This allows new values (i.e. new activities) to be added to this dropdown by the user. This all works fine.

However in the view these new values do not appear when a record is opened in edit mode. The edit form is the same as the entry form but the new values from the activities table do not appear.

Can the form that is called in the view edit-mode use the same dropdown values that the Entry Form does?

Thanks in advance.
