Hello everyone in this community!
I need help to create Perfect view of created Opsgenie alert 
Let me show details.
I have custom multi-select field Post-Incident Review Actions with 2 options:
- Investigation of financial losses
- Security team analysis

When I "ask" JSON payload

of Opsgenie+Jira Management integration for this CustomField data with {{ customFields.customfield_10189.value }}

I get this not beautiful, but quite informative output in created Opsgenie alert:

Can I filter this output to create clear and informative Opsgenie alert? I need to receive in Opsgenie created alert data from Value JSON payload.
For clarification: this output is enough for next steps (assign, route and so on) in Opsgenie.
I want to understand the filtering mechanism (if it can be used in this case).
Will be very glad for any kind of help.
