A button to always go back to the main report with selected filters

[ADiiit]

Dear gurus,
This is a bit urgent.
I have 5 different filters on the report page and 2 charts.
when I run the report it runs with the default prompt values and 1 chart is rendered.
From the 1st chart, I can drill down to another Level with applied filters, so now I see 2 charts- main chart and drill level chart
Now if I change the filters, the filter is applied to both the charts that appear on the page.
But customer want this filter to be passed to the 1st main chart which was rendered on 1st run and not on the current drill level page with 2 charts.
Cognos gurus, please advise.
