I'm trying to harvest a directory called Release however in my installer i want the files to be installed into "bin".

this is my Pre-Built Event Command line which I have add into my wix3.7 in Visual studio 2012

```
"%WIX%\bin\heat.exe" dir "$(SolutionDir)\Export\Release" -dr INSTALLFOLDER -cg ExportComponentGroup -var var.sourcePath -ag -sreg -suid -out "$(SolutionDir)\SetupProject\ProjExportDir.wxs"

```

how can i change the output from this:

```
<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Fragment>
        <DirectoryRef Id="INSTALLFOLDER">
            <Directory Id="dir813D1F0C17C6517DA1B9A933450C5B91" Name="Release" />
        </DirectoryRef>
    </Fragment>
    <Fragment>
        <ComponentGroup Id="ExportComponentGroup">
            <Component Id="cmp6711F65C37F4310E92A3213080231DA6" Directory="dir813D1F0C17C6517DA1B9A933450C5B91" Guid="*">
                <File Id="filABBC16CBAD4348690B2250C408181254" KeyPath="yes" Source="$(var.sourcePath)\3AWrapper.dll" />
            </Component>

```

into this:

```
<?xml version="1.0" encoding="utf-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Fragment>
        <DirectoryRef Id="INSTALLFOLDER">
            <Directory Id="bin" Name="bin" />
        </DirectoryRef>
    </Fragment>
    <Fragment>
        <ComponentGroup Id="ExportComponentGroup">
            <Component Id="cmp6711F65C37F4310E92A3213080231DA6" Directory="bin" Guid="*">
                <File Id="filABBC16CBAD4348690B2250C408181254" KeyPath="yes" Source="$(var.sourcePath)\3AWrapper.dll" />
            </Component>

```

I have tried using -directoryid flag however this isn't working.
