Variable stream matching

I have an issue with data stream matching. How do you combine two lists into one with variable output?
For example, if my inputs are a list with two branches - 42 and 43 values respectively and 16 branches with one value each, how could i change the input B (curve) to make my outputs 42,43,42,43…, instead of 42,43,43,43…

Thanks in advance!

Use Longest List components Wrap setting

Don’t know what I’m doing wrong but its giving me the same list…

Who knows? No screenshot, no files :man_shrugging:
