Bulk input or import from spreadsheet of time entries for multiple cases

Some of our timekeepers use other systems (excel, separate word document, or even hand written notes) to track time. Staff is then used to make the formal time entries into the Neos system. Inputting these entries one at a time is very laborious and inefficient. Having a way to either type-in, or maybe even better import from a propertly formatted spreadsheet, multiple entries in one step would be a major timesaver.
