[TYPO3] how to make dmailsubscribe use 2 languages

[Bartek]

Hi!
As far as I know by default this ext uses the template located in 
typo3conf/ext/direct_mail_subscription/pi/fe_admin_dmailsubscrip.tmpl 
but doing so it can use only one language. My question is if it`s there 
a way for it to use beside it a german version of template eg. 
typo3conf/ext/direct_mail_subscription/pi/fe_admin_dmailsubscrip_de.tmpl

thanks in advance
regards
