Thank you May.
Oh, so it is not a core, but a 3rd party feature then. In that case, I am not sure if we will be able to support this. The plugin only has a few hundred users, and have not been updated for over a year. I am all in for supporting 3rd party software, but this may take a huge amount of time for a very little potential user base.
I am very sorry to say this, if this was a core feature within WordPress, then I would definitely make sure to support in it’s full extent, but in this case that is probably not going to happen.
