How can I force sampler load order on huge workflow?

I have a very large workflow that uses a ton of latent blends, latent multipliers, SVD modifications, and like 6 power noise ksampler advanced nodes I'm testing. Everytime I start the workflow it decides to start with a different sampler or take different paths during the workflow, so it crashes with OOM every third time I run it or so. When it actually runs it's pretty great and I will share this when it's done.

Someone mentioned on reddit you could use "highway" nodes whatever that is, but I think he's offline this week and hasn't responded back. Not sure if that's an extension for comfyui.

So basically asking, how can I force which sampler starts first and also how can I force the path a latent takes if things split off multiple times with latent blends, loop back around to other samplers, maybe pause a latent on a node to wait for next latent to come though for blend then continue, etc.

Edit: Okay I think I found it https://github.com/Trung0246/ComfyUI-0246 but how can I force the first sampler that starts, as I have multiple different models going to different samplers and it randomly decides which to start first.
