When using Time from now in table for time, I try to change value of 1st and 2nd row

I’ve data from influxdb2 and user grafana 8.5.0.
As you see on the screenshot I’ve a table for visualization. In column one i’ve the time with unit “Time from now”.

Now I want to show the words today in column one row one and yesterday in column one row two.

Is this possible with a transformer or with overriding? I couldn’t find anything.

the closest solution that you will find fo something like that is regex-based value mappings:
