Yes, we don't have this particular feature built into NTM 1.0 at the moment. We are looking at this functionality, If we do have it into our next release, would you be happy to join our mock-up calls or a Beta release ?
As a work around, I would recommend the following which can help.
1. If you have already discovered the network and mapped it. You can use Edit -> Edit Map Properties to show you the credentials you feed in and correct it if necessary.
2. If you want to generate maps for a different network with the same credentials.
Save the first map with a name. Then go to Edit -> Edit Map Properties and you should see your feed credentials. Change Network Selection accordingly and under Discovery Settings give it another Map name.
Yes, would be happy to join a beta release.
