When using Keywords for restrictions (week, month, year, etc) it would be helpful to use a syntax of (Month) - x where 'x' is the number of days to subtract from the keyword. For example on 2/6/2019 (Month)-1 would give ((2/1/2019) - 1) or 1/31/2019. This way the user can specify the values of 1/1/2019 - 1/31/2019 by using Month-1 for one value and (Month)-1 for another value. The number of days ('x') should be able to be variable. For example if you want to set a value to the 7th of every month, you would use (Month-1)+6 to get 1/7/2019.

Also, not sure if this is already possible but would be nice if Month-'y' that 'y' could be any number. For example, If we wanted to use values to get the last 3 months of data, one would use (Month-3) to (Month)-1 to get 11/1/2018 to 1/31/2019.

Thanks for a solid project and I hope these suggestions can help make the product even better.

Thanks so much!
