Hi @ben6, thanks for your patience.
I’m afraid the current plugin functionality doesn’t provide a possibility to use dynamic values in gradient fields. Sorry about this inconvenience.
We will check how feasible it will be to add the requested feature to the future plugin update, thank you for suggesting it. Once any news will be available - I will let you know.

Hi @ben6, good news here 
.
We have pushed a plugin update, that has added the option of working with dynamic sources and in a Repeating Group.
To check changes, please upgrade your plugin to the latest version (Version 1.3.0 “added dynamic color source & an option to use in RG”) and give it a try.
Let me know if there is anything else that I can help with about our plugins 
Have a nice weekend!
Regards,
