Dependent date filters in report

[IrfanYasar]

Dear Community

I have a problem that I need your help with.

Initial situation:
Table 1 = Contract data with 2 date columns (start and end)
Date table 1 = Simple date table with "ADDCOLUMNS" and
"CALENDAR" formula --> has a relation to "Start" in table 1

In the report, a slicer can be used to set the filter individually to the date table 1 with "Start".

However, I only want to display the values that are dependent on date table 1 but affect the "End" column.
= 8 months before MIN date and 2 months after MAX date

Problem
If I create an additional table and set the start and end date as a measure of date table 1, the calendar does not start with the selected filter.

How can I generate either a new table, a new column or a new filter that filters the end date?

The filter does not have to act on a measure, but on the entire report page.

Of course, the best thing would be if I could change the 8 months before and 2 months after with a slicer (per month).

Thx! 🙂
