How do I expand bounds on Grid 2D Gas Smoke Fire emitter?

Hello! I’m currently trying to put together a scene involving fire VFX using a slightly modified version of the Grid 2D Gas Smoke Fire emitter. I can’t figure out how to expand the bounds so that the smoke doesn’t get cut off, as seen below. When searching through all of the modules, I can’t find anything that adjusts the yellow box to allow for the effect to be larger. Thanks for your help!

I’m having the same issue, did you ever resolve this?
