Produce target file names that reflect target language

It is possible to automatically produce target file names that reflect the target language of the file? For example, a source file named "SOURCE FILE" is processed through Trados from English to Spanish. Ordinarily, the target file will generate as "SOURCE FILE" and so will be indistinguishable from the source file. I would like to create a setup whereby the target file produced automatically reflects the target language so in this case would look instead something like "SOURCE FILE_ES".
