Problem adding multiple signatures when signing msi package

[ToshB]

I've set up electron-forge with the @electron-forge/maker-wix maker, and I'm attempting to sign it. It fails consistently with the following error

[FAILED: Signtool exited with code 1. Stderr: SignTool Error: Multiple signature support is not implemented for this filetype.

I've run the build with debug logging enabled, and it seems to sign successfully with sha1 first, but then fails when it attempts to sign again with sha256 (see attached log). As far as I can tell from the source it always tries to sign with both sha1 and sha256, even when the filetype apparently doesn't support multiple signatures.

Perhaps the signing algorithms could be made user configurable, so I can specify only sha256 if I don't want to double sign my package.
