Custom Parametric Analysis

Hello everyone,
im trying to use SKILL or ocean script to make a parametric analysis that takes user a defined inclusion list, but mine runs much slower than the one in the Analog Design Environment. Because mine runs a new DC simulation for each parameter. But the one in ADE runs only a single DC sim and uses the parameters with that single simulation results(as far as i understand). I extracted the script by Save Script menu item in parametric analysis and when i copy and paste that exact code, it runs very slow because of that problem i mentioned. I consumed myself but cant get anywhere. I would be very glad if some experienced person knows what to do to do it exactly like ADE does. Thanks a bunch!
