As you probably know we regularly add user driven features to Kendo UI development plan along with those that are already on the road map. The decision whether а feature will get implemented or not depends not only on it's necessity, but also on the requests and votes of the users.
Regarding your specific case, a syntax like this is not available neither in Kendo UI Grid nor in Telerik Grid. This is the first time we are receiving such inquiry and that is why I suggested you to submit it in Kendo user voice portal
so other users could evaluate and vote for it. If this feature becomes popular with the users, we will consider adding it in a future release.
