BIP Schedule Data Parameters for the Previous Month

Content (please ensure you mask any confidential information):

I am looking to use date parameters on a BIP Schedule that will get the date for the first day of the previous month, and the last day of the previous month that I can use to pass into the report as it runs. Are there Date parameters I can use on a scheduled BIP report to Get the First Day of the Previous Month, and the Last Day of the Previous Month?

The only dynamic functions I see are below, but they only fetch the current month, whereas I need values from the Previous month.
