Update alternative weights dynamically

[StefanFPF]

Hi,

we want to give our business users the ability to dial up/down the weights of alternatives dynamically (ideally through the split dashboard, but could be a separate tool or UI). I'd like to verify if this is possible with the current Split API. I tried saving the experiment after modifying the weights (experiment.save and/or alternative.save), but when reloading the experiment, the changes didn't take effect. What is a or the best way to accomplish this? We want to decouple deployments from the experiment change schedule.

Thanks
