Filtering to Ignore Specific Rows

Good morning everyone,

I have a spreadsheet to organise promotional activity for our customers, organised by month. I have divider rows to separate each month to make the spreadsheet easier to read, but as you can probably guess, this doesn't work too well with filtering.

Is there a way to force excel to ignore these rows? See below image example, row 408.
