FCCS - Pipeline - Is it possible to use variables in a 'Business Rule' type job

Summary:

I'd like to use variables for the parameters of my business rules.

Content (required):

I created a pipeline containing one job: 'Translate'. This is a 'business rule' type job.

I added the parameters used by the business rule (e.g. 'Entity' and 'Period') and I added the value (e.g. 'Jan' for the 'Period).

Instead of adding the value (e.g. 'Jan' for the 'Period'), I'd like to use a variable. This way, when I submit the pipeline, I can fill in the variables which will be use by the jobs in the pipeline.

Is it possible and if yes, how can I achieve this?
