Is the only way to move the transitioner name into a custom field to write a script?

Question

Is the only way to move the transitioner name into a user picker custom field to write a script?  If so, how do I write and apply the script?  My post functions are:

1. Set issue status to the linked status of the destination workflow step.
2. Add a comment to an issue if one is entered during a transition.
3. Update change history for an issue and store the issue in the database.
4. Re-index an issue to keep indexes in sync with the database.
5. Fire a Issue Created event that can be processed by the listeners

1) I saw documentation that says I can use the custom field name instead of "customfield_10037".  Do you think that's correct?  Again, when I tried that, it didn't work.

2) If I try "customfield_10037", for which I assume I'd have to find the custom field Id and substitute it for 10037, where can I find the Id?

3) Is initiator.accountId the equivalent of the transitioner, and is 'accountId' sufficient, with no Id replacing it?

{
"fields": {
"customfield_10037": { "id": "{{initiator.accountId}}" }
}
}

When I tried to publish the rule, I got an error:

Additional fields contains invalid field(s) in 'update' or 'fields' section: Business Analyst Signoff

I resorted to selecting the field (not More options > json), and selecting myself as the value.  That worked.

What was wrong the the json I created (same  as your example, but with the name of the field instead of the field Id)?

1) It would appear that I can't simply select the custom field and update it; I have to select the advanced option, correct?

2) In the documentation for advanced, I see that I can use the actual field name instead of a field Id.

3) The documentation appears to indicate that the accountId is a smart field, and works as written.  Is that correct?  If I get as far as activating the workflow and trying it out, I may get my answer.
