Select region to run bitbucket pipelines in

We have a project where we build a docker image in Bitbucket pipelines which then must be uploaded to a container registry in China.

However, uploading the image is very slow from bitbucket's CI/CD servers which, based on this, are hosted in the US.

If we could choose where to run Bitbucket pipelines, we could pick a region close to where  we need to deploy our images and drastically reduce the time needed for our CI/CD pipeline.
