Building a macro

I have a cloud based Portfolio Management System (Advent APX) and I would like a macro/script to be able to run a date range of the same report. Presently it only allows for me to run single day reports. I think it should be fairly simple to build but I am not very efficient building macros. I have attached a report that allows for one day at a time. I would like the ability to run this report over a span of at least 30 days (so it would start at 12/31/2020 and I could choose both the starting date and ending date. Please provide an idea of how long it would take to build as well the approximate cost. Thank you.
