Any option to connect to rinkeby network insted of ropstain

Hello, Im interested on use OpenSea Market in our project, they work for test on rinkeby testnet.
Is there any option to connect server instance with Rinkeby testnet or only local and Ropsten Testnets? Thank you so much. You are the Way!

All networks which are currently fully supported are in the drop down menu when creating a new server instance. New ones will be added once our nodes have finished syncing (which takes a while!). If you go to the status page here you can see the progress. I don’t see rinkeby in the list as of yet, but it will likely be added at some point.

Thank you so much lets build!

Rinkeby add would be great! And thank you for working on it.
