Filter condition for Webi report scheduling

Hello,

I have a Webi report with a query that has one filter (it states the starting and ending date of data to be displayed in the report). This report has to be scheduled but it has to contain different filter values each time the report is run.

I'd like to know if there is a way to schedule this report taking into account that each iteration of the scheduling process has to use different values for the filter.

On the same way, the Webi report has a XY diagram with a text title made up of a fixed literal label. Is there any way to inject the text title from the scheduling process (in order to avoid editing the report before each scheduling iteration occurs)?

Thanks a lot!
