Jenkins - Dynamic Extended Choice option to populate multilevel select list

Is there a way to use a dynamic (modified) Extended Choice parameter to bind with an Extended Choice Parameter multilevel box to populate a first level list box?

For example, if I had:

It will link to this box below:

If you have the first level (Choice) by default with their choice ModedChoice (Choice1, Choice2, Choice3) or based on their choice ModedChoice, Value1 will be filled (in which case I would choose the choice level).

I know that the second method I was talking about could be done for a single picklist as described on the wiki and it will look for a text file Choice1.txt, Choice2.txt, etc. that will contain the values ​​Value1 ( i.e. key = value1.1, value1.2, value1.3, etc.).

I could not figure out how to have this key containing a multilevel list as it is a tab-delimited format for separating columns i.e.

Choice    Value1    Value2
choice1    value1.1    value2.1
choice1    value1.1    value2.2
choice2    value1.2    value2.1
choice2    value1.1    value2.5
choice3    value1.2    value2.7

      

        
        
        
      

    

etc..

I tried something like (Choice1.txt):

key='Value1    Value2
value1.1    value2.1
value1.1    value2.2
value1.2    value2.1
value1.1    value2.5
value1.2    value2.7'   

      

        
        
        
      

    

etc. for Choice2.txt and Choice3.txt.

But that just fills in the tiered level with Value1 Value2

.

I tried binding to another Moded Choice (Multi Select) and left the Key field blank and kept the appropriate tab-delimited format for the multi-level select list, but it still outputs Value1 Value2
