I create a sub-task and get the summary by copy the summary value from trigger issue and add a few word.
eg. trigger issue summary is " test_wip_finance" ,the ideal new sub-task summary would be "test_wip_legal" .
However, now I got "test_wip_finance_wip_legal“ by using {{triggerIssue.Summary}}_wip_legal . How to exclude the redundant word "_wip_finance"
