How to compare servers on different time scales on the same graph

Hi there, I am wondering if Grafana supports displaying metrics on the same graph for two different servers on two different time scales.

i.e Server 1 CPU from Day 1 to Day 7 and Server 2 CPU from Day 5 to Day 8 on the same graph

I know there is a timeshift function in each graph that can be updated on each individual graph but if i have mutiple graphs it is cumbersome.
So i suppose my real question is…is it possible to define a timeshift function as a variable for the dashboard.
This would mean all graphs i defined for Server 1 could use a different timeshift variable than Server 2.

Sorry if this question has already been asked i couldn’t find it mentioned on any of the forums.

Thanks in advance for any help you can give!!
Mark.
