So I tried searching to find if anyone found a way to do Inclusions instead of Exclusions. After not finding anything I dug into the code myself and found a pretty simple and fast solution for the category, product, manufacturer, customer and shipping zone exclusion/inclusion options.
 
In catalog\includes\classes\discount_coupon.php
 
To change categories, products and manufacturers
 
on lines 225 (category check), 247 (product check), 274 (manufacturer check) change:

return false;
 
to:

return true;
 
And on line 290 change:

return true;
 
to:

return false;
 
 
To change customers
 
On line 66 change:

if( tep_db_num_rows( $check_user_query ) > 0 ) {
 
To:

if( tep_db_num_rows( $check_user_query ) == 0 ) {
 
 
To change shipping zone
 
On line 80 change:

if( tep_db_num_rows( $check_user_query ) > 0 ) {
 
To:

if( tep_db_num_rows( $check_user_query ) == 0 ) {
