Connect multiple SAP BW to same netweaver portal

Dear Experts,

I'm a SAP BW Integrated Consultant and I have to developp a planning application for a customer.

There are only 2 environnements for BW : Development and production.

As I started lauching transaction RSPLAN from development system, I noticed that the portal that was launched was not connected with dev but with production.

What I would like to know is if it is possible to connect my BW dev system dans my BW prod system to the same netweaver portal. If yes, how to do that assuming that BW prod is already properly connected to the portal.

Thanks in advance for you help.

Christophe
