That is not a problem as you can add additional repositories to one checkout (If you create a local git repository for example it has 0 remotes. When you check something out from Bitbucket it has 1. But you can also add another one like e.g. the Ionic one). The docs actually tell you how to do that and how to use it.
However now I can see that migrate to Ionic Pro dasboard was not a great idea because the app Ionic View for Android doesn’t still support Ionic Pro projects
