Looker Studio date reporting

Work with me for up to two hours to finish development of a Looker Studio report comparing landing pages with a date control. Report columns: Landing page, previous vs current sessions, change, and percent of change (heat mapped), with the periods selected by the date control.

I have the blend done on Google GA4 data, and the report started.

Must work with Ultraviewer, Anydesk, etc., and do the work on my workstation.
