Hey guys, we know that we can use a variable to rename output files after their input e.g. #{input}, by using the "rename dataset" action in the workflow editor. However, we would like to use these variable as a workflow parameter too, e.g. for the "Add or Replace Groups" tool as the ID tag, so the ID would be the dataset name. Currently we have to specify read groups for 190 datasets and doing this manually would take a long time, so we would prefer to automatize it. Is this possible? Thanks for any advice.
