insertObject + REPLACE or ON DUPLICATE KEY UPDATE

[sandomatyas]

Hi
I like to use insert/update records with insertObject/updateObject like this: https://docs.joomla.org/Inserting,_Upda ... _an_Object

But sometimes I need a REPLACE or ON DUPLICATE KEY UPDATE version of insertObject
Is it possible to do this somehow simply? I can check it with a select but there should be something more elagant for that.
Like a replaceObject method or a fourth param for insertOjbect()
