Is there a callback event while user select different texture set in the Texture Set List?

Community Beginner ,

Hi, thanks for reply
I am working on a python plugin to manual control all the silder value in Mesh map by using our product,
We noticied that there isn't a callback event to get the notification that user change to other texture, or we didn't find it?
Is there any other work around that we could be able to know that the user's currently activate stack has been changed?
Thanks for any reply!
