How to increase the limit of people showing up in feast?

In the game, there is a limit of people showing up in the castle, I think it's around 15, including the guards. Thus during the feast, even there are more than 20 lords come and join, only half of them can show up in the castle. It would be great if there is a way to increase this limit, like make it to 25 or 30, it's good to have the crowded feeling, it's a feast!

I have tried the default editor in the game, found there are couple yellow circles in the castle, but not sure how to add one. I am quite sure that each yellow circle represent a position for a character to show up.

Could someone share the knowledge and teach me? Thanks!

Thank you very much, taking a look now

                                          Its creepy scary how most of the ladies in a feast all look alike-clones in 1257 A.D.,so more clones for you.
