run_model only fo redesign points

[benL18]

Hi team,
first of all thanks a lot for developing and maintaining this fantastic tool.
I am starting to work with it to improve my practical experience with engine modelling and it's really great!

one question: how can you run a model only for a new point? let's take the high_bypass turbo fan example

the command prob.run_model() will always run the 3 cases 'DESIGN', 'OD_full_pwr' and 'OD_part_pwr'

how can we run them sequentially in 3 steps: first run DESIGN and then run one case or the other?

I imagine this would speed things up in the generation of decks like @flight-test-engineering has done

thanks a lot for the help
Benoit
