Resume optimization

[Puumanamana]

Hi,

Is there a way to resume a saved sherpa run? I noticed there was a load_dashbord() method, but it also says "currently this study cannot be used to continue the optimization".
Moreover, I was wondering if it was possible to start with a given algorithm (e.g. random search), save the study, and resume it with another one (e.g. Bayesian optimization).

Thank you!
