Not sure :)
If I read you correct you mean :
-table has no records yet
-textboxes have controlsources as alias.fieldname
-And you want to edit them

If that's the case no you cannot. You should use some workarounds. ie:
-Add a custom property to form called oRec
Select myTable
scatter name thisform.oRec

-Change controlsources to thisform.oRec.FieldName

When saving you could gather name Thisform.oRec as appropriate.
