Deployments using Bitbucket Pipelines

We do deployment of code from Bitbucket repository to different environments.

I think the following features are required in Bitbucket Pipelines when deploying:

1. A flag which controls/triggers the deployment of code as soon as someone commit the code to branch. I do not want deployment to happen as soon as someone commits the code to the repo.
2. Scheduling the deployment.
3. A button click to trigger the deployment ( as it was in Bamboo cloud). I feel that this is the much required feature as we can do deployments whenever we need it.
