Hey Daniel,
such functionality isn’t available within our Dashboard yet, but I’d be more than happy to share your request with our Product Management team, so they can reconsider its implementation into the Platform.
In the meanwhile, you can check our SDK and particularly the Dashboard Plugins part below:

I understand, this might not be a suitable workaround for every user, since it is mostly aimed on developers, but I hope that you will find some hints there as well.
