Is it possible to specify automerge / automergeType on a custom manager?

How are you running Renovate?

Self-hosted Renovate

If you're self-hosting Renovate, tell us which platform (GitHub, GitLab, etc) and which version of Renovate.

Bitbucket

Please tell us more about your question or problem

In the renovate documentation about Advanced Capture, this example is used:

# renovate: datasource=github-tags depName=node packageName=nodejs/node versioning=node
ENV NODE_VERSION=20.10.0

I know how this works and used it successfully, but we want for some dependencies that we trust to automerge using the branch option and for others we want to create a PR. Is it possible to define this at the customManager level? e.g. like this:

# renovate: datasource=github-tags depName=node packageName=nodejs/node versioning=node automerge=true automergeType=branch
ENV NODE_VERSION=20.10.0

and then capture it in the customManager. would that work?

If not, what would you suggest?

You need to define that using packageRules
