We are building up resource calendars in a outside tool and wish to export in xls format for use in schedule leveling in Microsoft Project.

Can resource calendars be imported into MS Project 2013 from Excel? I'm able to import task and basic resource info (resource sheet data) into Project, but I haven't seen a way to import either full resource calendars, resource group calendars, or multiple available.from & available to combinations.

Thanks in advance.
