Can we put only of the running Oracle instances in one server to SDT?

Hi @Mike Moniz,

 Thanks for your response. I apologize for not properly paraphrasing my question. 
Actually we have multiple datasources for DB monitoring, and under each one of them there are multiple DB instances. 

Now if one particular undergoes a maintenance window, we have to manually go inside each of the datasource’s discovered instances and put them in SDT. That’s a tedious job. 
So we were looking to see if there’s any efficient way of doing that.

Thanks
