How do we reset data prompts from Bex query

Hello,

We are building a PowerBI dashboard based on data in an SAP BEx query.  When I pull the data into the dashboard there are prompts that are required.

Once these prompts are entered the appropriate data is pulled from SAP BW.

Is there a way, once I create the dashboard, to change these prompt values?  I have not been able to find an option to do this and these prompts will need to be updated monthly.

Thanks much,
Andrea
