Custom agent and Model choice when start implementation from plan mode in cloud

### Describe the feature or problem you'd like to solve

Custom agent and Model choice when start implementation from plan mode in cloud

### Proposed solution

We have this, when we choose "Cloud" instead of Local, which is awesome! Thank you for that.

Could we have that for the "Start implementation" -> Cloud as well?

Currently if you choose "Continue in cloud" it just hands it over without any control over what agent or model to use.
