It is possible but it is too much to describe here. You will need to 
change your $TCA for this. Details can be found here:

Look for "requestUpdate" in "[ctrl] section" and "foreign_table_where" 
for "select" field. Basically you mark one field as "requestUpdate" and 
feel values in another field from this field when form is loaded. It is 
easy.
