One way to handle adding properties to SCATTERed objects may be to approach this from the other side. You can replace the native SCATTER command with your own function MYSCATTER which may work on any area

* myScatter.PRG
myScatterObject = CREATEOBJECT("myScatterObject")
IF !EMPTY(ALIAS())
	lnFields = FCOUNT(ALIAS())
	FOR N =1 TO lnFields
		myScatterObject.ADDPROPERTY(FIELD(N), EVAL(FIELD(N)))
	ENDFOR
ENDIF
RETURN myScatterObject && Always return an object, so GATHER command could not choke.

DEFINE CLASS myScatterObject AS SESSION
* Optionally you may define the native PEMs here as HIDDEN 
ENDDEFINE

Then you go to the record you need and:

SELECT mytable 
scattered1 = MYSCATTER() && This is instead of SCATTER NAME...

* .... && more code here

* Now add a property using the native AddProperty method and assign any value to it.
scattered1.addProperty("newPropertyName", "This is the new property value")

SELECT othertable
GATHER NAME scattered1 MEMO 

Note that you still can use the native GATHER command here.
The scope of scattered1 variable and other code safety features are up to you.
