How to output files with custom names.

[pessimizor]

I am working with analyzing and splitting up a video into multiple files, i.e. working with the Video and Image Processing Blockset.

I wish to have the files have custom names with variables extracted from the analysis. However, the block "To Multimedia File" I am using to output the new video files doesn't seem to allow any variables in the Output File Name.

Could someone throw me a tip?
