Relative time into panel

Hi, I’m in Grafana free Cloud…
and I got this little problem.

I’ve a google sheet data source, and my data start from February, 4.
So How can I cope with a time specifica in a panel like that one below? is it possible?

Some formula like:
now/y+35d (2023-02-04)

The time on piker is related and hidden for a master data table… I cannot touch it.

Thanks Alen
