In project structure > Build Variants > Build Variants > Build Types, you can hit the '+' button to add a new type.

If you enter one with a hyphen (e.g. debug-custom), it generates invalid gradle code in your build.gradle:

    buildTypes {
        debug {
        }
        release {
        }
        debug - custom {
        }
    }
 

And prints the following error in the build output:

Could not find method minus() for arguments [BuildType_Decorated{name=custom, debuggable=false, testCoverageEnabled=false, jniDebuggable=false, pseudoLocalesEnabled=false, renderscriptDebuggable=false, renderscriptOptimLevel=3, minifyEnabled=false, zipAlignEnabled=true, signingConfig=null, embedMicroApp=true, mBuildConfigFields={}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}}] on BuildType_Decorated{name=debug, debuggable=true, testCoverageEnabled=false, jniDebuggable=false, pseudoLocalesEnabled=false, renderscriptDebuggable=false, renderscriptOptimLevel=3, minifyEnabled=false, zipAlignEnabled=true, signingConfig=SigningConfig_Decorated{name=debug, storeFile=/usr/local/google/home/ccraik/.android/debug.keystore, storePassword=android, keyAlias=AndroidDebugKey, keyPassword=android, storeType=jks, v1SigningEnabled=true, v2SigningEnabled=true}, embedMicroApp=false, mBuildConfigFields={}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}} of type com.android.build.gradle.internal.dsl.BuildType.
