Timesheet : several improvements are needed

My company has begun using the Timesheet capability in Wrike beginning of this year. Unfortunately, our employees face a number of worries. Would it be possible to improve your application so that we are able to :

• Drag & Drop columns to change their order (display)
• Show weekends & holidays in GRAY cells
• Export the data in Excel (I know we can do it with the Time log but the display is not the same. We like having tasks & column for each day)
• Copy/Pasta the data (with different format Ex.: 4.5 instead of 4h30 so we can create formulas)

• View or export for more than a week. Ex. a month (because our billing is monthly) OR Create a report with the same view as the timesheet (column/day), with filters for date, user, project, etc.
• Enter more than 24h per day. When we started Wrike, we already had a number of projects underway. It would be interesting to be able to enter, in one shot, the number of hours already invoiced on the project. That way, our project tracking would be real, and not just based on entries made from the start in Wrike. It's impossible for us to go back and enter the hours, 24 at a time, as some projects have been underway for more than a year OR Create a field where hours can be entered and added to the field TIME SPENT

Many thanks in advance.
