SAP DMC POD Designer

Hi gurus,

there is a way for extending one of the standard plugins of the POD Designer tool?

I am able to create new custom plugins but i would like to know if i can extend standard.

Is there the possibility to add plugins inside the header of a POD? I tried but it seems it is not possible to customize it and i am not able to remove it for changing it using a plugin.

Thanks in advance
