Transform usage - How to push event for all specific terms even if one of them is missing

Hi Team,

I have a scenario. I have a transform created that groups all events of each day from the source index into 3 different status - Completed, Terminated and Retry. For example, if for 25th Apr 2021 we have Completed - 3, Terminated - 5 and Retry - 1, then destination index has 3 records for 25th Apr as shown below.

{"keyword": "Completed","Count": 3, "Per day": "2021-04-25T00:00:00.000Z"}
{"keyword": "Terminated","Count": 5, "Per day": "2021-04-25T00:00:00.000Z"}
{"keyword": "Retry","Count": 1, "Per day": "2021-04-25T00:00:00.000Z"}

This is all working as expected. Now, if there is no Retry events for 26th Apr, transform has following in destination index which is again as expected.

{"keyword": "Completed","Count": 3, "Per day": "2021-04-26T00:00:00.000Z"}
{"keyword": "Terminated","Count": 5, "Per day": "2021-04-26T00:00:00.000Z"}

But the problem is I need to push the data from destination index to another output(Kafka, in my case) for all the 3 cases, including one for the missing Retry. So, effectively I want to push to Kafka 3 events as shown below(including one for Retry with count as 0) instead of 2

{"keyword": "Completed","Count": 3, "Per day": "2021-04-26T00:00:00.000Z"}
{"keyword": "Terminated","Count": 5, "Per day": "2021-04-26T00:00:00.000Z"}
{"keyword": "Retry","Count": 0, "Per day": "2021-04-26T00:00:00.000Z"}

Not sure how this can be achieved. Any suggestions/inputs here will be very helpful.

Thank you,
