burn: Use same file for two ExePackage elements (Upgrade v3 to v4)

[mistoll]

In v3 I used the following snippet to install SQL Express:

<PackageGroup Id="SqlExpress">
  <ExePackage Id="SqlExpress" DisplayName="SQL Server 2019 Express"
    Cache="keep" Compressed="no" PerMachine="yes" Permanent="yes" Vital="yes"
    Name="SQLEXPR_x64_ENU.exe"
    SourceFile="SQLEXPR_x64_ENU.exe"
    DownloadUrl="$(var.SqlWebLink)"
    DetectCondition="SqlInstanceFound"
    InstallCondition="INSTALL_PREREQUISITES=1"
    InstallArguments="$(var.SqlPackParameters) /ACTION=Install $(var.SqlInstanceParameters) /Q /HIDECONSOLE /SkipRules=RebootRequiredCheck"
    UninstallArguments="$(var.SqlPackParameters) /Action=Uninstall $(var.SqlFeatureParameters) /Q /HIDECONSOLE">
    <ExitCode Value="3010" Behavior="forceReboot" />
  </ExePackage>
 <ExePackage Id="SqlExpressUpgrade" DisplayName="SQL Server 2019 Express Upgrade"
    Cache="remove" Compressed="no" PerMachine="yes" Permanent="yes" Vital="yes"
    Name="SQLEXPR_x64_ENU.exe"
    SourceFile="$(var.DownloadsDir)SQLEXPR_x64_ENU.exe"
    DownloadUrl="$(var.SqlWebLink)"
    DetectCondition="NOT (SqlInstanceFound AND (SqlVersion &lt; v15.0.0.0))"
    InstallArguments="$(var.SqlPackParameters) /ACTION=Upgrade $(var.SqlFeatureParameters) /Q /HIDECONSOLE /SkipRules=RebootRequiredCheck">
    <ExitCode Value="3010" Behavior="forceReboot" />
  </ExePackage>
</PackageGroup>

The Idea behind that is to have different arguments on (first) installation and on upgrade.

In v4 this produces the error
The CacheId '9774C72F4A0D16FA4473138E7F02CEEA62908C6D5E5D757EBE4C09ABA7999B7C' for package 'SqlExpressUpgrade' is duplicated. Each package must have a unique CacheId.
If I add a CacheId Attribute the error becomes:
The external Payload 'SqlExpressUpgrade' has a duplicate Name 'SQLEXPR_x64_ENU.exe'. When building the bundle or laying out the bundle, the file will get overwritten.

If I change the name the file would be downloaded and cached twice, which is not what I want. Is it possible to use the same file for two ExePackages in v4? How?
If not, are there other options to switch the InstallArguments?

No, you can't use the same file for two ExePackages in v4 because it doesn't work properly at runtime.

The CommandLine element can be used to provide conditional arguments to an ExePackage.
