I'd like to request a way to manipulate a large amount of cell groups in the Kendo UI Spreadsheet without decreasing performance. For example, I'd like to be able to merge/unmerge and change font size to multiple specific cell groups. I understand changing multiple DOM elements at the same time can cause sluggishness, but maybe there's a way to reduce the time. Currently, it's taking a long time to completely load.
Thank you for investigating.
