I am in block editor but why I don't connect to the BlockPlaceHolder please?
I want to create this block dynamic : https://www.youtube.com/watch?v=BEz24YfwVAM

I search in the commands out of the block I choose the block and I obtain this with Y position:
%<\AcObjProp Object(%<\_ObjId 2502722928>%).InsertionPoint \f "%lu6%pt2">%

With \_ObjId 2502722928 is the instance of the block but each time the instance is different.

How to change this with a shortcut of the the block himself like this please ? :
%<\AcObjProp Object(%<ObjId.self>%).InsertionPoint \f "%lu6%pt2">%

EDIT 2 : %<\AcObjProp.16.2 Object(?BlockRefId,1).InsertionPoint \f "%pt2%.30q0%ct8[0.001]">%
