Some people have been wondering how to get their custom reports they built into the new CRB. I'll try and give some instruction here.
First, the problem. The reason your reports aren't automatically in the new CRB is that we moved the files to a sub folder. In the old CRB the reports were all in /admin/reports/[tab name]. We could have kept that location but then all the people who imported into Custom Page Management (CPM) would need to manually delete all those files one by one. That's a very time consuming task and one that the plugins will prevent in the future. But we wanted to make it as painless as we could for the CPM users and so we followed the advice of Matt Freund and moved all the files to a new location so that you would only need to delete a few files. To keep things simple we moved them to a subfolder of the folder they were already in. The new path is /admin/reports/CRB/[tab name]
Moving files in custom/web_root
If you use the custom/web_root method for your custom pages here is what you'll need to do.

What about updates?
Updates to each plugin will no affect your custom page. Moving to plugins allows us to now mass delete files in CPM and mass add files in CPM when we need to without having to delete each file one by one. But deleting the plugin doesn't delete the folder so the file(s) you add are safe.
If you create a file and a future update adds a new file with the same name then the plugin will not install. It will warn you that the file already exists and to remedy that (by either removing that file from the plugin or removing the existing file from CPM). This is a huge improvement because the old method of importing into CPM would blindly overwrite any files in its way. So if we added a file to the bundle that matched your custom file name it'd simply overwrite yours with ours with no warning at all. Now you have to choose which is a much safer way of doing it.
I hope this explanation helps those of you who made your own reports into the bundle. If I'm missed a step feel free to comment below.
