How to change variable value based on another variable


Im creating something like “environment status” dashboard with status for each application in our company. We have “prod” and “test” environment. I have dropdown env variable to choose the right environment. However, one application has environment “dev” mapped to “test”. So I need in this specific application panel, when “test” env variable is selected, use the “dev” value inside the query. I tried the key-value custom variable, but it didn’t work as I needed.

Could you please help?
