1:1 interleaved T/F change to m:n T/F

Currently the design I've got shows a 1:1( n:n) interleaved on-chip transformer.The windings are connected in series.
However now I need to implement a m:n transformer. I've tried editing the script and manage to get something: For example, when i key in Primary Turns=3 and Secondary turns=5, the outcome I will get is P1,P2 and P3 but S1,S2 and S3 are grouped together(connected in parallel) then S4 and S5. Ultimately it's still 3:3.
So now i have to edit the script to have the secondary turns connected in series but i'm not sure as where/how to go about doing it.

Can anyone help/guide me with this?I'll be glad to share the script for reference.

Feel free to clarify to question.

Thanks!
