Any suggestions for Workflow validation or Custom Field for a company-managed kanban board?

[Michelle Yip]

Hi Atlassian online community!

I'll appreciate any help I can get, looking for suggestions to refine my current workflow in a company-managed kanban board. I'm trying to see if there's a way to automatically bring a ticket that's created as To-Do, to In Progress so that it appears in the active board. My use case around this is to bring visibility to critical bugs detected quickly in the active board, so there's no need to dig through the board to find the ticket and bring it up. 

Also, welcome any suggestions on how I can better refine a Custom Field that I've set up, I am lacking the knowledge to setup the validations for this field to actually work.
