Is it possible to back shade every other day of the week on the Time Card?

Does anyone know how, in 25C, to better differentiate the days of the week on the Time Card? Presently, the excel view of the Time Card has no clear delineation between days. We are new to this implementation, and users are desiring a clearer delineation. Whether with back shading or by thickening the lines of the columns at the start and end of the represented day, anything would be better than the flat view it currently has. Thank you!
