Thank you for using Syncfusion products,
We would like to let you know that currently we do not have support for your requirement.In EditControl, formatting option has been kept separately based on the selected languages and format types. Alternately we can achieve your requirement by using the showcustamization dialog box.We have created a custom sample for your requirement and it can be downloaded from the following link.
