Have ResourceEditor some mock/generic AOW Unit Property for requisites filtering?

[DudenJuden]

Hello all,
Currently I am trying create mod with two .rpk files.
The first file contains few AOW Unit Properties. The second file contains a AOW Unit Property Group which contains properties above.
I want to make these properties forbidden for units with certain requisites, but do not want add them in properties as forbidden because want to use properties in other mod and in other way. From my point of view, the best way is add requisites in AOW Unit Property Group instead. Unfortunatelly, I can't do that as AOW Unit Property Group doesn't have Requisite Filter. So, I have a few questions:
1. Does it possible to use some mock/generic AOW Unit Property which can filter requisites and contains other AOW Unit Properties?
2. If not, does it possible update data structure of AOW Unit Property Group with new fields ( Requisite Filter ) from my side?
3. From my point of view it is totally wrong but... If also not, can I create and use some script like Trigger Condition Macro to decide if AOW Unit Property is acceptable for AOW Unit? How the script can be integrated?

Thanks in advance.
