Multi Select Variables

I have to display some information in a table format. I have added multiple dashboard variables, to filter the data. Variables are of the custom type with multi-select enabled. Options inside the variable has multiple values separated by pipe(|), , for example, Option1: val1|val2, Option2: val3|val4|val5, and so on. This works fine when we select a single option, but when multiple options are selected, they get concatenated by a comma instead of a pipe, like val1|val2,val3|val4|val5 which is causing the issue. Pipe is mandatory as I am using regex in flux language.
