is there any global path to an .wim file?

i'm triying to build an recovery app, in a multiple partition HDD, but, in XML file, in this section under image install:

 <DataImage wcm:action="add">
                    <InstallTo>
                        <DiskID>0</DiskID>
                        <PartitionID>1</PartitionID>
                    </InstallTo>
                    <InstallFrom>
                        <Path>C:\winre.wim</Path>
                    </InstallFrom>
                    <Order>1</Order>
                </DataImage>

but as you can see, "c:\winre.wim" is located in "C", is there any joker parameter for not having to forcely specify a drive path to the wim file?

(something like "%drive%\winre.wim" )

any kind of help is appreciated.
