DMN should collect all output from child DMNs

Hi,

I would like to evaluate multiple decision tables in one Rule Task. I know about the DRD and chaining the DMN tables. But I don’t want to use results of one table as inputs into another. I need results from both tables to use later in the process. And I would like to avoid creating two Rules Tasks.
Ideally I would like to get results from all tables as a List/map under one variable.
I have 3 child dmn. Where one of child dmn evaluation is list and it return list of output and other dmn just return one or two output variables. I want to configure literal expression in parent DMN in such a way that it should give me just all the output from all child dmns.
Please find attached my DMN.
parentDMN.dmn (5.3 KB)

I have read one of solution here but it didn’t work for my use case. Specifically for DMN where I have to evaluate it for list of inputs and return list of output

ThankYou for the help!!!
