Pass arguments to Execute Workflow node

When starting a workflow with a Webhook trigger node, one can pass query parameters into the web hook URL, and then use these (e.g. in an IF node), something like this:

{{$node["Webhook1"].data["query"]["reset"]}}.

Now, if I have a workflow, which includes Execute Workflow nodes, I want to be able to pass arguments into this node, similar to how I would pass query parameters into a webhook URL. Is this possible?

Please check always first if the question got already answered already before posting:

We now also added that to our documentation:
