So for Ludum Dare 44 I used https://marketplace.yoyogames.com/assets/479/room-dog this to load rooms within a room. I made a game called 99Hearts where I hand crafted the rooms but the player gets them shuffled in a random order and lays them down. This was really awesome but the extension I used was not designed for gms2 so it had some limitations like I couldn't even use the tile-set functions in the room editor. Everything had to be an object.

Anyways people seemed to like this game and the concept so I have been thinking about working on it making it a proper game rather than just a gamejam game. I was curious if GMRoomPack would be able to allow me to place rooms I prebuilt into a larger room at runtime. 

Here is an example of the room placing in action to get an idea of what I'd like to know if it's possible with GMRoomPack . If I am understanding things correctly I believe it will but wanted to double check
