### What needs to get done Provide a mechanism for using different source on different architectures. ```yaml parts: my-app: plugin: dump source-type: deb source: # If I run `snapcraft build` on amd64, it will use amd64 version of deb as source. amd64: target/my-app_1.0.0_amd64.deb # Or if I run on arm64, another deb will be used. arm64: target/my-app_1.0.0_arm64.deb riscv: target/my-app_1.0.0_riscv.deb ``` ### Why it needs to get done Hi community, 👋🏼 I'm a collaborator (only **Triage**, without write access) of repository [clash-verge-rev/clash-verge-rev](https://github.com/clash-verge-rev/clash-verge-rev). I'd like to implement an integration of GitHub Workflows to build a `.snap` for the application. In previous jobs & steps, we already built and signed `*.deb` files for users. Those steps are running using strategy matrix on `ubuntu-22.04` with different architectures (`amd64` and `arm64`). Built release also have these kinds of suffix (`_amd64.deb` and `_arm64.deb`). We want to build different snaps for different architecture, so different architecture uses different `source` in `snapcraft.yaml` parts. Is this currently supported? Or can community implement this feature? 🙏🏼
