The functionality you describe is not supported by the Kendo UI Calendar API.
I encourage you to participate in the Kendo UI Feedback and Feature Request Portal
, where it has already been requested
, in order to voice your opinion; if the feature proposas gets enough votes, developers will take notice and might implement it in future releases of Kendo UI.
Alternatively, you could take advantage of our professional Feature Customization Services
; you can read more about them here
I hope this helps.
