Heya there,
I'm currently looking for some ways to pre-populate our mandatory Summary field. We will need a specific structure for the headline (summary), that's the reason I want to have it pre filled with: %customField1% : %customField2:
1 would be for example the issue type and 2 would be the name of the company.
How can this be achieved with Jira Cloud? I have found some articles but found nowhere a way how to do it exactly. 
Thanks
