SAP Lumira Prompts in Freehand SQL?

Hello,

Is it possible to have prompts using freehand sql as a datasource when using Lumira?

For example, my reports would typically have a datasource that is a stored procedure, with parameters passed to the stored procedure. Can this be done at all with Lumira, or will we need to bring all the data back and then filter somehow for one particular region.

If so, does anyone know how to pass filter values possibly through the url/open document equivalent?

Thanks!
