Advice on time tracking across projects

Hi,

I've noticed that time spent/estimates do not aggregate between issues in different projects.

I am wondering if this will be added in the future?

Also, is there is a way of emulating it in workflow?

I have tried the following but cannot find a way of using the 'Spend time' field or parsing its contents into a command...

rule make time accumulate across projects

when Spent time.changed {
  for each source in issue.subtask of {
    message("Subtask for: " + source);
    source.applyCommand("add work Today " + Spent time + " This is a test");
  }
}

I looked at the string operations, but I don't know how to convert 'Spent time' to a string, even though it will be displayed in messages like 'P1DT3M' - 1 days 3 minutes.
