Hi Team,
Could you please let me know below if it's possible in Jira.
We have two custom fields
1. Intake Type (select list)
2. Impact Location (checkboxes).
When a user select option from select list ( ex: network), and if one option is selected on checkbox (ex: US) a issue related should be created in another project (name : Infra project). If the user select two options two issues should be created, if three options selected three issues should be created and if the user select (ex: Global option) a total of 5 tickets should be created in Infra project. 
Note: The tickets in other project should be created during a workflow transition in first Project.
Thanks
