Greater flexibility in Relative Date filtering

I have a visual where I would like to show the current month to date and the whole of the previous month. I thought I would be able to do this with Relative Date filtering but I can either select 'is in this' > 'month' or 'is in the last' > 'calendar month'.

Please either add the option to have more than one relative date filter with AND/OR options, as there is for advanced filtering, or include an option under 'is in the last' > 'calendar month' to include the current month as well.

Thanks
