As a QA Engineer, I need single cmd to run DJS test with different themes

Is your feature request related to a problem? Please describe.
Currently to run DJS tests vs theme x we use npm run test:delayjs:x. will be great to be able to run specific scenario with different themes using single cmd

Describe the solution you'd like
A clear and concise description of what you want to happen.
Either update the related scenario so we loop on it by the number of themes or bash file to run with different themes

Additional context
Add any other context or screenshots about the feature request here.

• Having the flexibility to have file contains list of themes and related slugs so it be used automatically will be great
