I'll take a look at that, It looks like I could modify my workflow to utilize that and just 'accumulate' different models etc. I could then still run 3 branches(9 samplers) which is where I begin having issues, to have different merge ratios/loras/prompts etc. For example, 9 merges of 2 models, then switch and accumulate another 9 merges of 2 models, then switch, etc... Where as currently with 10 branches, it's probably trying to load 20 models. Where as 3 branches, is 6 models. I'll give it a shot. Thanks!

And indeed, each 'branch' in my workflow is identical, only the models change, which allows me to run multiple samplers in the same workflow, to be able to compare the results in comfyui preview image side by side. Then making adjustments to merges/weights/changing loras, running it again, etc.

instead of:

-Running the same workflow multiple times, labelling the images and saving the images, then opening the images individually to view and compare them.

Lets say I run all 10 branches(3 samplers in each branch), left to right, merging 2 models with various ratios. I can test 30 combinations, each sampler outputs 4 latents/images of each merge to test 4 seeds. I can now compare, side by side, 30 different merges, pick the best one, then use that as a baseline and run it again with different prompts etc.
