Can you add "extra" field to FilterableSettings to allow the user to set extra globally for all columns in a grid?

Currently, if I want to set extra to false for a column, I need to do something like this:
<kendo-grid-column field="ProductName" title="Product Name">
<ng-template kendoGridFilterMenuTemplate let-filter let-column="column" let-filterService="filterService">
<kendo-grid-string-filter-menu [extra]="false" [column]="column" [filter]="filter" [filterService]="filterService">
</kendo-grid-string-filter-menu>
</ng-template>
</kendo-grid-column>
But it would be simpler if we can do filterable:{extra:false} just like Kendo UI for jQuery. https://docs.telerik.com/kendo-ui/api/javascript/ui/grid/configuration/filterable.extra
