I need to install a missing node without updating ComfyUI backend

[Lainier]

Since a few weeks ago I could not generate WAN 2.2 videos because ComfyUI was eating my 32GB of VRAM, slowing the process tremendously. I fixed it by rolling back ComfyUI to v0.22.0 (commit a8d2519). But after SwarmUI's commit 32e1eae I'm getting a new error when using the video extend feature: there is a missing node which can't be installed. I can avoid the node error by reverting SwarmUI to commit fe97691, but is there a way to keep SwarmUI updated and install the missing node without updating ComfyUI?

I am having the same problem. Current Comfyui is completely broken now - I cant generate LTX anymore after recent updates - either its taking ages (>10x times than before) or I get OOM. I rolled ComfyUI back to 0.22.3 which works for me. After last SwarmUI update I get several errors on startup:
