Feature request: Saving and resetting filters

Hi all,

I am working on a project, where it would be nice to save the filters that are currently selected. I can then save and load filter presets, which is nice to have in certain use-cases.

Currently, it was easy to get the filters by creating a public property for the criteria list. But when I try to set the criteria list again. It is not updating all the filters and the view again. Can anybody help me with this implementation?

Currently, I edited something like this in the Filterdatagrid.cs:

public Dictionary<string, Predicate<object>> Filters
{
    get => criteria;
    set
    {
        // reset criteria List
        criteria.Clear();
        GlobalFilterList.Clear();
        
        criteria = value;

        CollectionViewSource = System.Windows.Data.CollectionViewSource.GetDefaultView(ItemsSource);
        if (CollectionViewSource.CanFilter) CollectionViewSource.Filter = Filter;
        CollectionViewSource.Refresh();


        OnPropertyChanged(nameof(Filters));
    }
}

I can get the filters by requesting FilterDataGrid.Filters, but when setting, it will not work.
