InfoPath Dev

I am working on a new combined meeting agenda and report form and need to populate into the form a field that can display all the members of a given sharepoint user permission group so my supervisor can check a button to say they attended or not. so far I am not seeing it when searching that it can be done, anyone ever attempted anything like this?

Maybe take a look at this post: https://www.infopathdev.com/forums/t/38584.aspx - it is older, but has a document attached to one of the posts on how to get SharePoint group info and suggestions for how to copy the data into your main data source.
