I'm trying to use the keyword for restrictions. Month-1 gives me the start of the last month. But what if I'm trying to get the first and last date of the previous month? For example, if I run the report on 2/4/2019. I would like to put in keywords that give me dates between 1/1/2019 and 1/31/2019.

Thanks for the quick reply. I'll put in a feature request. It makes the most sense to do a calculation after the fact. On 2/6/2019 to set the dates to the 1st and 31st of January you could use Month-1 for one value (1/1/2019) and (Month)-1 for the second value (1/31/2019). This way you could also set a value of the 7th of every month by using (Month)+6. In addition Month-2 should give you 2 months back. Not sure if this works or not, but would be helpful to use for screens where the user wants to see the last 3 months worth of data.
