You can accomplish this with some CSS: https://gist.github.com/cdcharlebois/efc6c0cdaea08f3352c7fa43ceda7307
/* add the "dg-checkboxes" class to your data grid in studio pro */
.mx-datagrid.dg-checkboxes tbody tr:after{
color: red;
font-size: xx-large;
position: absolute;
left: -15px
}
.mx-datagrid.dg-checkboxes tbody tr.selected:after{
content:"☑";
}
.mx-datagrid.dg-checkboxes tbody tr:not(.selected):after{
content:"☐";
}
I have a simple suggestion
Convert the Data grid to List view
In the list view add a check box and map it to a new boolean attribute
