Can I get the theoretical maximum power form PV module uing SIMULINK in other radiation values rather than 1000 irradiation (because it is the only value SIMULINK block of PV array can plot(?.

I want to ge the values of theoretical maximum power at different irradiation and temeprature values. When I use the command "Plot" inisde the PV array block in suimulink, it gives me an option for only 1000 irradiation and different tempeature or 25 temperature with different iradiation. I ant to drwa the curev at 20 degree and 800 irradiation. How can I do this?
