Cannot disambiguate between multiple questions with the same name

Nobody has claimed this yet.

Hi,

I'm trying to use `uefisettings` to flip the `Multi-VC` (Enable/Disable Multiple Virtual Channel) option in my UEFI's settings, but because this option is present for each PCI-e root port (up to 3), the question appears three times with an identical name:

```bash
sudo ./uefisettings hii list-questions | grep -B 1 -A7 'Multi-VC'
```
```
Question {
name: "Multi-VC",
answer: "Enabled",
options: [
"Disabled",
"Enabled",
],
help: "Enable/Disable Multi Virtual Channel",
},
--
Question {
name: "Multi-VC",
answer: "Disabled",
options: [
"Disabled",
"Enabled",
],
help: "Enable/Disable Multi Virtual Channel",
},
--
Question {
name: "Multi-VC",
answer: "Disabled",
options: [
"Disabled",
"Enabled",
],
help: "Enable/Disable Multi Virtual Channel",
},
```

When I try to use `uefisettings hii get`, only the first question is returned (note only the first is `Enabled`):

```bash
sudo ./uefisettings hii get 'Multi-VC'
```
```
GetResponseList {
responses: [
GetResponse {
selector: "899407D7-99FE-43D8-9A21-79EC328CAC21",
backend: Backend::Hii,
question: Question {
name: "Multi-VC",
answer: "Enabled",
options: [
"Disabled",
"Enabled",
],
help: "Enable/Disable Multi Virtual Channel",
},
is_translated: false,
},
],
}
```

Is there any way to select the question to get/set more granularly such that I can choose the other questions?

Thanks in advance,
Luke

Start with the `hii get` and corresponding set command handling shown in the issue, then trace how questions are matched by name. Define a selector that distinguishes duplicate `Multi-VC` questions, and consider the work complete when each duplicate can be independently retrieved and updated.
