Start on a Controller or Sampler

### Use case

We can start a Threat Group with right-click -> Start.
It would be an incredibly high time-saver to be able to do the same on a Controller or a Sampler (HTTP Request in my case).
Could this be added?
Thanks a lot

### Possible solution

Start an HTTP request by right-clicking on it and Start

### Possible workarounds

Currently, when I want to test a request, I have to disable all other ones before starting the complete Threat Group. Heavy, especially when it's in a controller in the middle of a lot of others samplers.
