Combining two measures and adding an IF

Hello, I am still new to power BI and how its formatting works so Im not sure how to accomplish this. I have two measures:

SinglePOs = 
  VAR PO = MAX(PO_PurchaseOrderDetail[PurchaseOrderNo])
  VAR PREVPO = CALCULATE(MAX(PO_PurchaseOrderDetail[PurchaseOrderNo]), PO_PurchaseOrderDetail[PurchaseOrderNo] < PO)
  VAR Rec = MAXX(FILTER(PO_PurchaseOrderDetail,[PurchaseOrderNo] = PO),[Received])
  VAR PREVREC = MAXX(FILTER(PO_PurchaseOrderDetail,[PurchaseOrderNo] = PREVPO),[Received])
  VAR Qty = MAXX(FILTER(PO_PurchaseOrderDetail,[PurchaseOrderNo] = PO),[QuantityOrdered])
  VAR PREVQTY = MAXX(FILTER(PO_PurchaseOrderDetail,[PurchaseOrderNo] = PREVPO),[QuantityOrdered])
  VAR Req = MAXX(FILTER(PO_PurchaseOrderDetail,[PurchaseOrderNo] = PO),[RequiredDate])
  VAR PREVREQ = MAXX(FILTER(PO_PurchaseOrderDetail,[PurchaseOrderNo] = PREVPO),[RequiredDate])
RETURN
  IF ( [QTYAvailable_SumFinal] < 0 && Qty < ABS([QTYAvailable_SumFinal]),  Rec & " " &PO & " " & Qty & "pcs " & Req & " " & PREVREC & " " & PREVPO & " " & PREVQTY & "pcs " & " " & PREVREQ,  Rec & " " & PO & " " & Qty & "pcs " & Req )

& another

SplitPO = 
  VAR PO = MAX(PO_PurchaseOrderDetail[PurchaseOrderNo])
  VAR RowCount = CALCULATE(COUNTROWS(PO_PurchaseOrderDetail),
                    PO_PurchaseOrderDetail[PurchaseOrderNo] = PO)
  VAR FirstReq = MINX(FILTER(PO_PurchaseOrderDetail,PO_PurchaseOrderDetail[PurchaseOrderNo] = PO),[RequiredDate])
  VAR Qty = MAXX(FILTER(PO_PurchaseOrderDetail,PO_PurchaseOrderDetail[PurchaseOrderNo] = PO && FirstReq = PO_PurchaseOrderDetail[RequiredDate] ),[QuantityOrdered])
  VAR SecondReq = MINX(FILTER(PO_PurchaseOrderDetail,PO_PurchaseOrderDetail[PurchaseOrderNo] = PO && PO_PurchaseOrderDetail[RequiredDate] > FirstReq ),[RequiredDate])
  VAR SecondQTY = MAXX(FILTER(PO_PurchaseOrderDetail,PO_PurchaseOrderDetail[PurchaseOrderNo] = PO && SecondReq = PO_PurchaseOrderDetail[RequiredDate] ),[QuantityOrdered])
RETURN
  PO & " " & FirstReq & " " & Qty & "pcs" & " " & RowCount & " " & " || " & SecondReq & " " & PO & " " & SecondQTY & "pcs"

I basically need to combine these two and have a check at the top that checks the RowCount variable. If it is >1, then I need it to run the SplitPO measure. If it is just 1 row, then it can run the SinglePOs measure. Is this possible to do?
