### What should this feature add?

Add the ability to use wildcard files with dynamic prompting. It looks like the node [could have had it](https://github.com/invoke-ai/InvokeAI/pull/3533), but it was not added because there was no way to handle the path to the wildcard directory. Could this option be added in now?

> Wildcards via wordlist files
Implemented, but we don't have a simple way to handle the path to the wildcard directory yet, so I didn't include it. This is super straightforward to add back in later.
