Is it possible to get the last (successful) workflow run as an input variable?

[chgl]

Is it possible to get the date of the last successful workflow run as an input variable? I'm looking at doing something like the cron-backfill example (https://github.com/argoproj/argo-workflows/blob/master/examples/cron-backfill.yaml), where a workflow is run multiple times a day and receives a timestamp range of data to process for the current day.

I'm currently running the following every hour, processing changed data of the current day multiple times:

              arguments:
                parameters:
                  - name: BEGIN_DATE
                    value: "{{ workflow.creationTimestamp.Y }}-{{ workflow.creationTimestamp.m }}-{{ workflow.creationTimestamp.d }}"
                  - name: END_DATE
                    value: "9999-12-31"

It would of course be cleaner to just process the data since the last successful run (in case it keeps failing throughout one or more days). Is something like workflow.lastSuccessfulRun possible, or is there a better pattern?
