Can you set individual MPP set points for mulitple input inverters in PV Designer?

The PV Designer inverter data base includes inverters with multiple DC inputs and MPP trackers.  For example, the Mastervolt Sunmaster XL15 has 6 DC inputs and 3 MPP-trackers.  In PV Designer,  the assumption in the simulation model is always that all of the strings are combined in parallel and supplied to a single DC input.  Thus separate MPP settings for individual strings are not supported in the simulation model at this time.
