As far as I know this is not possible.
I can recommend creating a PCB-Decal with just one pin, where you have defined the padstack as needed.
Save this PCB-Decal as 'New_Decal' in the library.
When you need to create a new decal you can use this as a kind of template.
I do about the same. I have different "Decal templates" from which I start from.
