builk part question

I am trying to set up a bulk part system to be used in assemblies. for example we purchase hose in bulk rolls but cut off sesctions to length and we do not want to create specific part numbers.  I intend to use configs of the bulk part and I want to include the length via text input into the qty column of the bom but I cant get a suffix to display in the cell ie 5M.  is there a way to achieve this?
