How to Create a Fixed Sliding Time Window (D-45 to D-15) in Zoho Analytics ?

Hello,

I would like to create a report in Zoho Analytics based on a sliding time window between D-45 and D-15, with a fixed snapshot of that specific period.

The data displayed should strictly reflect activity recorded between D-45 and D-15 only, without being dynamically recalculated outside of this time range.

What would be the recommended way to configure this type of “sliding but fixed” time window in Zoho Analytics (using relative date filters, date variables, custom formulas, or another approach)?

Thank you in advance for your guidance.
