Use of Custom Attributes in XML nodes

Hello!

I’m taking my first steps in Knime, currently trying to convert an XLSX file into an XML. When using the XML Row Combiner node, I would like to add a Custom Attribute with “today’s date” but I can’t find a way to run any sort of command/function that will return this. Does anybody have experience with that? I could use some advice on how to tackle this.

Thank you!
