Can Tivoli (TWS) be used for scheduling WebI reports in BO XI 3.1?

I am trying to figure out if it is possible to schedule WebI reports to refresh using TWS?

We are using BO XI 3.1 SP2 deployed on unix and would like to use TWS to refresh WebI reports that are built on SAP BW Bex queries. Does anyone have any experience scheduling WebI reports using TWS with XI 3.1? Any information you can provide would be appreciated!

Thanks,

Derek
