We have a group that has about 40 different services. To secure/confirm the trip we need to pay a deposit. For now this deposit nees to be spread out to 5 of the 40 services since it's just a deposit. Instead of doing this it would be nice to highlight all the services and just get a final total and from that pay a deposit. Then all entries show as final but only once we pay the final euro balance could they all change in paid.
