KNIME autorefresh

I’m fairly new to KNIME but I was wondering if there is a way for a KNIME workflow to update the input file itself periodically.

I’m creating a dashboard in power BI and it uses information from several excel trackers that get updated daily. I’ve done the data transformation and that will be the data input for Power BI. Is there a way for KNIME to automatically refresh the workflow either on a daily or weekly basis so the Power Bi dashboard is displaying up to date information?
