Deploying Templates To Multiple Spaces

I would like to deploy 1 Template to 3 different spaces (dev,stage,prod) but unfortunately in the YAML configuration ‘space’ is a top-level field which means it can only take 1 space at a time. If ‘space’ was under stacks then i could easily achieve this. I believe blueprints have the spaces under the stacks??

For Example:

stacks:
- key: dev

name: dev

space: dev-space

- key: stage

name: stage

space: stage-space

- key: prod

name: prod

space: prod-space
