【Canvas】Add fixed relative time-range (rolling window) option for multiple Charts on Industrial Canvas

Hello Cognite team,

First of all, thank you for your continuous development and improvements to CDF.

I'd like to share one feature request based on our daily use of Charts and Canvas.

Our use case In our long-term operation monitoring work, we create multiple Charts for different monitoring items and paste them onto a single Canvas, so that we can monitor many Charts together in one place.

The issue The ability to select multiple Charts on Canvas and change their display period all at once is very convenient. However, when we open the same Canvas a month later and refresh to the latest data, the start time stays fixed at the point we originally set. As a result, the displayed time range keeps getting wider and wider over time, instead of showing a consistent window.

What we'd like We would like a feature that lets us refresh Charts using the same fixed period — for example, a rolling window of the last 1 month, 3 months, or 1 year — so the time range stays consistent every time we open the Canvas.

This is already possible in Charts by clicking the heart (favorite) icon, but the same capability is not available on Canvas. We would love to have the equivalent function on Canvas as well.

Thank you very much for considering this request.
