Can you suggest please : One single Datasource for Multiple server

Thank you for your assistance. 

But if my logic within would be changing for different servers

For eg:

Invoke command  - computername Server1 - scriptblock { Logic to Size of folder = x } 

Invoke command  - computername Server2  - scriptblock { Logic to Number of empty folder = y } 

Invoke command  - computername Server3 - scriptblock { Logic to Name of oldest folder = z } 

So still do we see a way out of this? 

Or then we have to create 2 separate Data sources?
