Share datasource?

I have a centralized prometheus working as federated mode that collects data from other prometheus.We are planning to create two Orgs 1)app1 and 2) app2 (reason being the centralized prometheus gets metric from multiple application).

Can I configure the localhost:9090 as the datasource for app1 and app2 organizations under different name?

Org1:app1 Datasource:app1-prometheus (http://loclahost:9090)
Org2:app2 Datasource:app2-prometheus (http://localhost:9090)
