excel vba - Use VBA to Update Conditional Formatting Ranges?

I'm trying to update the conditional formatting range for about 30 rows of data on a worksheet. Every month I update the data and I want to run a macro to adjust the ranges to incorporate the new month. I've already done this for my charts by updating the end of the series ranges by looping through the ChartObjects and SeriesCollection.

To do this on conditional formatting, everything I've found requires hardcoding a range (either a cell reference or a named range), e.g.:

With Worksheets(1).Range("e1:e10").FormatConditions(1) 

I'd prefer to just loop through the collection of conditional formatting for the worksheet, but I can't find any evidence of this collection existing in the Excel VBA Object Model. Am I missing something here?
