Timestamp for user permissions

Hi,

we use UAM to stage users’ progress through an online course. Users can proceed in a non-linear way and it would be really helpful for us to know exactly *when* a permission has been applied.

I have attempted to manually add an automatic timestamp field to the table uam_accessgroup_to_object but it appears that the whole table is cleared down and repopulated whenever a permission is changed.

Is there any way to retrieve this information? Is it something that is in the roadmap for future development?

thanks

Robin
