Thank you very much for the valuable feedback. For the moment, we don't have plans to provide such an integration control. However, I've added your request in our PITS
under the name "TreeView ComboBox Integration Control"
and it will be available for tracking and voting tomorrow the latest. If it receives enough votes, we will definitely consider implementing it. I've also updated your Telerik points accordingly.
