How to build panel templates

Hi i am monitoring my home heating/climate.
Therefore i use panels with different settings for temperature or humidity.
For example panel for the outside temperature needs a different min and max and thresholds than for an inside temperature.
Same is it with humidity.
Is there a possibility to create templates for panels, so that i have only to change the template to change all panels.
As an example for this is to add a new threshold or change the color.

Have you tried using the new Library Panel feature in Grafana 8?

With this, when you add a panel to the library, you can add it elsewhere as many times as you want, and then any changes made to that panel on any dashboard will casdade down to all the others. You can also later unlink them, too:
