When can I use Substance Painter as a node?

When can I use Substance Painter as a node?
Please allow Substance Painter to be used as a node.
I am a texture artist mainly using Substance Painter, Substance Designer and mari.
The above tools are often used together in the texturing process. I think it would be really effective if Substance Painter could be used 
as a node for freedom and convenience when switching between tools.
I would like to see the day when I can use Substance Painter as a node as soon as possible.

Hi,

Would you be willing to explain what is in your opinion/experience the best way to use nodes in a texturing workflow? What is the issue you are trying to solve? 

Thank you,
Kind Regards,
