The same way you usually do. It's up to your op how its operands are split into groups and how those groups are referred to. Being able to resize the list doesn't necessarily mean append operands. In most cases, I'd expect there is a variadic group. But I can also see an op with one optional operand. The use case I have has 3 variadic groups and 2 of them are modified.
