What are you trying to achieve?

I can use regular expression defaulting to .* to match any for some. However, I’ve some variables that are used as prefix or infix:
${prefix_variable}-.*.*-${infix_variable}-.*
The wildcard don’t work as it still enforce the label/field contains the static characters (e.g. separator, static prefix)
How are you trying to achieve it?
I don’t see how to build (and if this possible) the log stream selector part with given constraints.
