Hi @LeSlow, that depends on what you mean by "alter" the gates. One thing you can do is plug all the gates from the expander, and then move from one to another sequentially (or in other manners). This module is a 4:1 or 1:4 switch or anything from 1:1 up to 1:4 and vice versa.
Let me know what it is you want to do in more detail.
