How to perform a wild-card search in the parentOption of a cascading select field, cascadeOption

Question

I currently have a filter searching for blank fields in the childOption (2nd field) of a cascading select field. The filter is as follows:

cf[ID] in cascadeOption("X", none)

but the limitation here is that I have to create a new line in my filter for every parentOption, which creates a maintenance nightmare should the options change down the road.

Is there any way that I can perform a wild-card search to look for a 'none' value in the childOption, regardless of the parentOption?

I was thinking something along the lines of:

cf[ID] in cascadeOption(*, none) //but this doesn't work

I've even approched the idea of creating a filter listing every alphabetical possiblity (e.g. cf[ID] in cascadeOption("A*", none) -- but that doesn't work either.

Thanks!

Were you successful?

You may try looking into Script Runner - Scripted JQL Functions to build a new custom issuefield function that adds regex to cascadeOption.
