How to access a class within a new nuget package that is already installed in another project

I have two projects P1 and P2 in my solution.I created a private nuget package which I installed in project P1.

(manage nuget package - installing for folder location where the nuget package physically exist).

P1 project reference is also added in project P2.The classes/methods inside nuget package is needed in project P2 as well...

Installing the nuget package again in project P2 works fine without any issue.But everytime when I update my private nuget package, I need to re-install the nuget package in both these projects.

I want to reference the class/methods of nuget package in P2 using the 'P1 Project Reference' which already exist. So that when nuget package is updated, I need to re-install in only one project(P1).

Is it possible to achieve this...

Thanks for any help.
