Thank you for your reply.
We checked whether your scenario is possible, but unfortunately, it is not and there is not a workaround we can suggest.
However, we are planning a major refactoring of this control in order to improve its behavior and performance.
I apologize for the introduced inconvenience. If there is anything else we can help you with, do not hesitate to contact us.
All the best,
the Telerik team
