Thank you for your quick response and nice workflow!
As a matter of fact, I have created such a workflow.
However, I would like to use lowercase UUID in many other snippets as well.
So instead of creating a lot of workflows, I want to do that with the snippets-only feature.
And I use snippet viewer's hotkey apart from general Alfred hotkey.
It would be nice to have custom dynamic placeholder such as "{script:user_custom_script}" in the next major version 😃
