Creating a calendar in excel

Hi, I'm looking for someone who's able to create a more advanced version of the already available calendar that comes default as a template in excel. The goal is to create a great campaign calendar. The calendar must include: - A list with several potential input fields (that users can add more items to). The fields would be such as: start date, end date, country, author, category, campaign name. - A way to import the data from those input field in to a calendar. - A way to filter the calendar according to those input fields. - A way to list all relevant campaigns and authors in the output of the calendar, under each specific date. If there are several occuring during the same day, these should be able to be displayed. If this is something you're able to do, let me know.
