Setting java.import.gradle.home in multi-project structure via vscode variable

I have a gradle multi-project structure in which the gradle wrapper is only placed in the root project.
Since I want all sub-projects to use the same wrapper (and not e.g. my local installation) I set the java.import.gradle.home in my workspace settings.
Ideally, I want to set this variable as: java.import.gradle.home=${workspaceFolder}/.gradle/...
However, in the generated .settings/org.eclipse.buildship.core.prefs in the subprojects I can see that the path is only copied and the vscode variable ${workspaceFolder} is not expanded.

Is it possible to support vscode variable expansion in the extension?
Are there other ways to set the gradle wrapper path relative to the project path? Currently, I am using the absolute path in my settings file. However, this would need to be updated by other team members.

Environment

• Operating System: macOS
• JDK version: 1.11
• Visual Studio Code version:1.45.1
• Java extension version: 0.62.0

Steps To Reproduce

1. Create gradle multi-project
2. Set java.import.gradle.home using ${workspaceFolder}

Current Result

Vscode variables (e.g. ${workspaceFolder}) used for e.g. java.import.gradle.home are not expanded in the org.eclipse.buildship.core.prefs (hence throwing no such file exception)

Expected Result

Vscode variables are correctly expanded and correct path is shown in org.eclipse.buildship.core.prefs of the subprojects
