I know the Datagrid has the option to "select first" as an option so that when the widget is loaded the first option is pre selected.
However I would like the option to choose what options are chosen, this would be useful for when you are using a datagrid2 as a way to assign objects to an object.
My use case is assigning visitors to a visit, I can select them using the datagrid2 multiselect and then take the output list of visitors and assign them using a nanoflow, however if I then want to later on add or remove visitors I cannot show what visitors have already been selected and find a way to toggle them using a datagrid2
