[UI Script] How to define default Jira project

Hi

when I click on 'push' button from 'Test Result' pop-up window, then Jira integrated pop-up shows up.
Then I suppose to choose a specific Jira project from drop-down box to which I wish to assign a new bug.

Question: how do I setup a default Jira project for a specific TestRail project.
I mean when I click push button I wish to see already selected Jira project, not the drop down box with all the Jira projects.

Thank you.
