Linking in Powerpoint a diagram among many from ONE Excel file

[sleepingSatellite]

I have ONE Excel file which contains MANY diagrams.
If I want to import and link one of these diagrams in Powerpoint (with Insert - Object), I am automatically proposed to import the diagram which was active (selected) the last time I saved that Excel file (no alternative).
If then I open again the Excel file, select (only select )another diagram in the same file and then save, then the next time that I open Powerpoint and update the links I will find the newly (Excel) selected diagram in the slide, at the place of the one I had inserted originally.

Is it possible to link in Powerpoint one of many diagrams from ONE Excel file and maintain the link ? Or am I obliged to create as many Excel files as the diagrams are ?

Thank you
