Setting estimate to Invoiced

Hello all,

I am wanting to set estimates to invoiced using the APIs. This status is
not currently in the list, am I missing something or is there another way
to do this?

Why do I need to do this?
Although we provide estimates for time to complete a job, we actually
invoice against the time logged by our consultants on the project (created
from the estimate). Therefore, we don’t invoice against the estimate, it
never reaches invoiced, and we have a backlog of completed estimates and
can’t see the genuine potential work on the books.

Thanks in advance for any help
