Instead of Julian calendar, Can Do Spreadsheet Format?

I'm looking to describe something that may be best as a spreadsheet but thought I'd ask about making it happen with RedNotebook: instead of the Julian calendar appearance, can I set it up as a row and column? First row, across the top would be something like: Hourly, Daily, Weekly, Monthly, Yearly, 50 hrs, 100hrs, (etc). These will be the columns. Succeeding rows will have the items to be done at those times.
This is a maintenance schedule for a liveaboard sailboat and has many items to be cared for at various scheduled times. I like many of the features of RedNotebook, especially the export as html.
