Program Report to export members by day

I am looking to build out reporting on my 15+ programs.  I am wanting to see a daily breakdown of how many users were added to each program by day.  I am wanting to export it and build some reporting around it. 

When you run a report, it shows the total, but it won't let you break it down by day (unless you manually go through and export it by day).  Is there anyway around this?
