Dynamically Change Initial Value in Lookup Table

Dynamically Change Initial Value in Lookup Table

I would like to display the current lookup field selection as the initial value for the next form data entry. As an example this would be useful if entering multiple time entries for an employee (selected from a lookup table of all employees). This initial value would continue to display until a new employee name was selected.
 
Is there a way to do this with Deluge script?
