[galaxy-user] renaming dataset in workflow

Is it possible when renaming a dataset in a workflow to have it fill in the dataset number like the default labels? For example the default label may be "Filter on data 17". What if I want it to be "High coverage on data 17"? Could I put some special variable in the text to tell Galaxy to fill in the data number? If it isn't possible please consider this as a feature request. Thanks, Belinda
