How to add placeholder text in the filter box in datatable column headers in Primefaces

<h:form id="myForm">
    <p:dataTable id="myTable">

        <p:column id="column1" filterBy="column1" styleClass="watermark1">
            <f:facet name="header">
                <p:watermark for="@(.watermark1)" value="Watermark 1" />
                <h:outputText value="Column1" />

        <p:column id="column2" filterBy="column2">
            <f:facet name="header">
                <p:watermark for="@(#myForm\\:myTable\\:column2\\:filter)"
                    value="Watermark 2" />
                <h:outputText value="Column2" />


<p:watermark for="myForm" value="Watermark 1" /> 
will be simple solution if all the filter fields of the form use the same placeholder.
