### Search before asking - [X] I had searched in the [issues](https://github.com/apache/dolphinscheduler/issues?q=is%3Aissue) and found no similar feature requirement. ### Description Now we support 2 kinds of parameter definition. 1. System variable use `${}` 2. Time related variable use `$[]`, and in this variable we also support data calculate, like `$[add_months(yyyyMMdd,N)]` But now we can't support the case that we need concat a fixed value with a dynamic value. like `/tmp/${system.workflow.instance.id}` Do we need improve the parser to support more flexible definition. like `/tmp/$[yyyy-MM-dd]/${system.workflow.instance.id}` I has write some simple code and test, the design is like this.  ### Are you willing to submit a PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
