Is this even possible/supported ? triple "FOREACH" in one request

Questions

Hello, I have 3 lists and I would like to send FOREACH element request but grouped together in same order

FOREACH ELEMA IN LIST1
FOREACH ELEMB IN LIST2
FOREACH ELEMC IN LIST3

BLOCK:HttpRequest
LABEL:Http
url = $“Link”
method = POST
httpLibrary = SystemNet
customHeaders = postdata < ELEMA > < ELEMB > < ELEMC >
TYPE:STANDARD
“”
“application/json”
ENDBLOCK
END
END
END

It doesn’t go as I expected, instead of taking first elem from each list in order; first element from LIST1 with first element from LIST2 with first element from LIST3.
Instead takes first from LIST1 and goes through all LIST2 with that.

Any ideas? Thanks in advance.
