Hans, Thanks for your answer. I want to add a field which can be used to classify the time entries based on time but not rate. And this field will be informative for the user, but not for the customer. In industries where Shift work hours are used instead of standard working day hours, the user can easily check only which shift he/she is. Also you can have for example the same rate for Day shift and Evening shift, these fields are not related in most cases.
WDYT?
