Matrix output from a Measure that uses Virtual Tables

Here is the solution:

Measure =

VAR _StrtDate =
    EOMONTH(2023,12,1) + 1  

VAR _LeaseTermTotal = 
//    60
    _LeaseTermFirst + _LeaseTermSecond + _LeaseTermTransition

VAR _EndDate = 
    EOMONTH(_StrtDate,_LeaseTermTotal+1)

VAR _CalMth =
    GENERATESERIES (0, DATEDIFF (_StrtDate, _EndDate, MONTH ), 1  )


VAR Virtual_Table_1.0 = 
    ADDCOLUMNS(
        _CalMth,
        "Date",
            IF([Value]=0,EOMONTH(_DeploymentDate,[Value]),EOMONTH(_StrtDate,[Value]-1)+1)
    )
VAR Virtual_Table_1.1 = 
    ADDCOLUMNS(
        Virtual_Table_1.0,
        "@AcqCost_1",
            _AcquisitionPrice_First,

        "@GrossCF",
            SWITCH(TRUE()                                                                                                   ,
                [Value] = 0, -1 * _AcquisitionPrice_First                                                                   ,
                [Value] = _LeaseTermFirst + 1 && _LeaseTermTotal = _LeaseTermFirst, _ExitPrice_Scenario_First               ,
                [Value] = _LeaseTermFirst + 1 && _LeaseTermTotal <> _LeaseTermFirst,  _CashFlow_Gross_Second                ,
                [Value] = _LeaseTermTotal + 1, _ExitPrice_Scenario_Second                                                   ,
                [Value] < _LeaseTermFirst + 1, _CashFlow_Gross_First                                                        ,
                [Value] < _LeaseTermTotal + 1, _CashFlow_Gross_Second                                                       ,
                1234
            )
)

RETURN
[@GrossCF]

This provides the ability to generate a Matrix of Measures out of a virtual table driven by Parameter Slicer SELECTEDVALUES().
