Klipfolio - Set Custom Date Range


We are using Klipfolio for reporting and I am trying to set up Klips of data from Hubspot as they are currently in our Dasheroo account. In perticular, I am trying to pull the List Growth for the previous month (last month) and not the last 30 days. Klipfolio can’t help me set up this query and set a custom date range. I would like to pull the list growth size for say the last 60 days and then pull it for lest month (the first of the previous month to the end of the previous month). Can anyone help with pulling this query from Hubspot with a date range of the last 60 days?
