Expression Language - Customization of variable naming conventions

Hello Camunda community,

We have a project where by convention, process-variables are following kebab-case (lower-case, separated by ‘-’) naming conventions. For example: my-process-variable. However, it is not possible to use such a variable in expression language (delegation code or condition expression). Presumable it is because in EL, variable names are required to follow Java naming conventions, where ‘-’ ist not an allowed identifier. Is there a possibility to customise the Camunda EL support, in order to convert a variable from CamelCase to kebab-case before the lookup of the variable value?

Many Thanks,
Lars
