Hello, I’m struggling with some multiplication between data trees:

I have a tree like this (the most simple version, there can be any amount of the 3 different metrics):

```
{0;0}
a0a
a0b
{0;1}
a1a
a1b
{0;2}
a2a
a2b
{1;0}
b0a
b0b
{1;1}
b1a
b1b
{1;2}
b2a
b2b
```

And I want to multiply it by this (the length of this will always match the length of the highest level in the prior tree)

```
{0}
x1
{1}
x2
```

Such that it results in

```
{0;0}
a0a * x1
a0b * x1
{0;1}
a1a * x1
a1b * x1
{0;2}
a2a * x1
a2b * x1
{1;0}
b0a * x2
b0b * x2
{1;1}
b1a * x2
b1b * x2
{1;2}
b2a * x2
b2b * x2
```

I’ve tried all the combinations of simplification/grafting that I can find… I used (inelegantly) DuplicateDataMatch for a similar problem elsewhere but haven’t managed to make that work in this instance.

Any help would be appreciated

And sorry if my language is confusing, I haven’t got Grasshopper lingo down yet!
