This won't work, you can nest <multiple> tags but you cannot nest multirow data structures (and most of the time you probably shouldn't think of doing something like this since most of the time it means doing a second query for every row in the first query which is a formula for a disastrous performance).

you might see if the <list> tag will do what you need since embedding a list in an element of a multirow should work.

I tried using the <list> tag, but it looks like there's a bug when it comes to displaying the data. Even though I have a different list for each row of the multirow, the same list is displayed for each row (the list belonging to the last row).

For the <list> part of it I was expecting:

4 6 9 3 1
5 9 7 8 9 53 2
3 76 8

but instead I get:

3 76 8
3 76 8
3 76 8

I verified that the data is properly created using the multirow_to_list function to display the multirow internal structure.

Looks like you are not applying the list value to a multirow column but to a normal variable, which happens to have the value that you assigned to it last when the adp is built.

Are you referencing your list with @multi.mylist@ in the adp?
